Key Escrowing: History and How it Affects You Essay -- Technology Encr

Key Escrowing: History and How it Affects You Keys and key escrowing are important topics in the world of business today. If they are important in business why should you be concerned with them? This paper will cover what are private and public keys and key escrowing. It will discuss the benefits, disadvantages, issues of the past concerning these topics, and why you should have an interest in them. Private & Public Keys Private keys are mostly a thing of the past. They are simple and easy to have intercepted. The way private keys work is this: a message is written and encrypted by the sender using a key; next the receiver of the message is given the key along with the message; they are then able to decode what was written (Baase, 88). The problem with this is that there is really no need to encode the message. If you have to give the key to the receiver, why not just give them the message not encrypted? Public keys provide much more security. In public key procedure, public and private keys are made. The public key is given to whoever would like to write an encrypted message. Once the message is encrypted and sent to the receiver, they use their private key to decode the message. Only the private key is able to decode. Not even the public key is able to decode what it just encoded (Baase, 95). If the encrypted document fell into the wrong hands, that person would have no way of deciphering it. Only the person possessing the private key has the ability to read the message. The government does not like this because illegal activities can be planned or talked about through this method without the government having any knowledge about it. That is why the government came up with the idea of key e... ...does key escrowing mean to the common person? First of all, information that you provide to banks, insurance agencies, hospitals, etc. is confidential information that is encrypted when it is sent electronically. If someone acquired a key that was not meant to, your information could be spread or sold. Your privacy would be breached. This is also an easy way for the government to store information on citizens. If they have keys to all encrypted documents, they would be able to access information at any time whether necessary or not. The idea of key escrowing is to protect the country. Its main intention is to raise the level of security. Terrorists or criminals could be caught before a serious incident occurred. Works Cited Baase, Sara.

Welcoming Country

Today, Many people in our society have faced many challenges whether it is because of their religion, gender, physical ability and sexual orientation. The United states has always prided themselves to be an open and welcoming country that does not judge one another on any basis. Under this administration the challenges that many immigrants are facing have become greater than ever. Hate crimes against the jewish people have been occurring way more frequently now. Many people in the United States have Xenophobia where they think their country, and their way of life is far superior than everyone else's, and when someone comes in from another country they tend to not accept them or even want to talk to them. Since 911 happened people tend to associate every muslim as a terrorist and they come here to this country to get the opportunities that everyone else has and they are not getting it because Islamophobia. Many young black teens are at a disadvantage because many schools have the zero tolerance policies that end up pushing them out of the school and into the juvenile and the criminal justice system instead of giving them a chance and help within the school system. The United States has come a long way over the years from slavery, and not letting women vote but many improvements can be made for us to truly become a country that accepts all people no matter if they're black, white a women or gay. Furthermore if this country wants a better future for their children then we have to work on these issues and have to become more open minded when it comes to immigrants, religion, women, and people who are gay that are in this country. Women have also gone through struggles facing discrimination because of gender. They have being doing the same job that men do but a lot of the time they do not get the same pay. It was not until the civil war that women were even allowed to work. Women were not hired for jobs that were considered jobs for males. In the 1960's women only occupied two percent of managerial positions. This showed that gender discriminations was still prevalent.This portrait that women had to accept jobs which did not require high skill nor get high pay. Even with all these issues women were strong and gathered in groups to fight these issues. In time, gender discrimination against women in the workforce has alleviated. In 1963 the equal pay act for women was passed meaning that men and women doing the same job had to get the same amount of pay or it was illegal. Groups like The National Organization of women were formed to help women get the same rights that men had like being able to play the same sports in college. Women are essential to society because they are just as capable as men and they have proved themselves in the workforce time and time again. An important reason why people come to this country is to be able to practice their religion freely and openly without any prohibition, harm or even trying to be oppressed . The founding fathers of our nation came to this country to practice their religion. Although, one of the roots of immigration into this country was the search for freedom of religion, many entities have been discriminated as a people. If we take a look at our history, we can find some examples. One of them is General Ulysses S. Grant who issued an order to take out the Jewish people from states Tennessee,Kentucky, and mississippi that were under his control. Most of the states in the U.S do not let people of the same sex marry. Within the last ten years states have been letting up, and are letting gays and lesbians marry each other under the law. These people have been discriminated since this country has been formed . When HIV first came out it was known as a â€Å"gay man's disease † meaning that you had to be gay to get that disease. Donald Trump and vice president Mike Pence do not believe in gay marriage and this is another barrier facing the LGBT community. They have been targeted and bullied in many schools around the country. Sexual discrimination was seen in the armed forces. Commanders used to launch what they called â€Å"witch hunts† to find gay troops and boot them out of the service. Many citizens that do not have the physical ability have been left behind and not taken care of the way they should be. These people for a long time and still today get bullied in school, have no friends, and do not get the support that they need and deserve to be able to do the things that they want. A lot of times these people get harassed in the workplace because they do not have the same ability as others. To help these people out the government passed a law called American with disabilities act to ensure that people with disabilities get proper accommodation in the workforce and also get protection under being fired just solely because they are disabled. I have learned a lot in the course. All the issues that this country is facing surrounding racism and people accepting one another for who they are and what they represent. I have also been exposed to many different things like people's cultures and the hardships that they face on a daily basis. The class has made me more aware of how deeply discrimination exists in our society, and the struggles that people have gone through to overcome make our country a more acceptable society. I learned that we have gains but still have a long way to go. After taking taking this class I have become a better person. Fixing these issues that society fights as a whole is not an easy task. In order to make changes with have to start with our young generations, and make it an empathize in the school systems to teach and focus on accepting one another no matter what the circumstances surrounding that person. Once we make the citizens aware that no matter what we believe, or how different we look, or whatever sexual orientation and gender we may be we are all part of the human race. If we make these social changes starting with our young children then this country will get back on track to fulfill its promise of being a nation which accepts everyone no matter color, race, gender. Furthermore we have to elect politicians that follows these ideologies that we are looking to have in this country. Many people in our society have faced many challenges whether it is because of their religion, gender, physical ability, and sexual orientation. This country has come a long way from discriminating against these groups but we still have a lot of work to do if we want this country to be fully accepting of everyone. A lot of these issues that we face as a culture need to be stopped from the top down. If the president can become more open and tolerant of others then that would be a major step in fixing this mess between different groups. What I have discussed in this essay about the current trend of racism, sexism and discrimination is not new, As the famous adage goes†History repeats itself†. At the founding of our american democracy with the Declaration of Independence (`1776) and the US Constitution (1789)all men were supposed to be equal under the law. However, women did not receive the right to vote until the year 1919 with the adoption of the 19th amendment of the constitution. Most states did not allow married women to keep their property until the beginning of the 20th century. Prior to the 29th century , women's legal status was that of chattel- they were the legal property of their Husbands and fathers. The few women from the late 19th century to the mid twentieth century who were able to get law degrees, medical and engineering degrees found themselves underemployed because employers did not want to hire women in these professions. It wasn't until the late 1970 that most states passed discriminations law to protect bias agent gender. Historically, Blacks have also been discriminated the legal and political system of our country. Although the 13th amendment ended slavery in 1865 and the 14th amendment (1868)guaranteed equal protection under the law for all persons, segregation and the denial of voting rights to blacks and other racial minorities persisted until the adoption of the federal voting rights in 1965. Discrimination in job hiring and access to housing was also rampant until the adoption of the Civil rights Acts in 1964. Historically, many different immigrant groups were discriminated and prevented from entering the United States. For example, the chinese exclusion act enacted in 1882 prohibited immigration of all chinese laborers even though –ironically– previous generations of chinese laborers were exploited to build the great railroad system that expanded the wealth and growth of the continental United States. Many of these laws were not repealed until after the second world war in 1948. Other ethnic groups (e.g. Irish and eastern europeans) had strict limited quotas for entry into the United States. Finally, protection from discrimination based on sexual orientation has only recently been enacted by only 24 states. There is still no federal civil rights protection based upon sexual orientation. Hence, for example, in the states of North Carolina and MIssissippi employers can fire or deny promotions to gay employees. We should remind ourselves of this history as we put into perspective the need to recognize and address the current problems of discrimination based on gender, race, ethnic origin and sexual orientation.

Exploring How State of Matter Affects the Rate of Diffusion Essay

Introduction Diffusion is the random process by which particles distribute themselves within a container or medium. There are two factors that distinguish how substances move passively through membranes. The first factor is hydrophobic , a nonpolar molecule that can dissolve in a lipid bilayer and freely move through the membrane. However a hydrophillic molecule consisting of ions and polar molecules inhibit in their movement through the membrane making it a slower diffusion process. Selectively permeable, moreover, are charged atoms and molecules that are mostly blocked from traveling through the membrane due to the hydrophobic center. The purpose of this experiment was to test how the state of matter affects the rate of diffusion in a semi-solid vs. a liquid state. If the Potassium Permanganate crystals are placed in Petri dishes filled with water and 2% agar, then the crystals will diffuse at a faster rate in water than in the agar. The addition of the Potassium Permanganate crystals to the water and agar, there will be a result of more diffusion and more obvious color change in water compared to agar which will result in a slower less obvious diffusion. Materials The materials needed for this experiment are: One Petri dish with 2% agar and one Petri dish of water filled half way up to test the rate of diffusion. Also, two small crystals of potassium permanganate and one pair of forceps will be needed to place in the Petri dishes. One metric ruler will be need as well to measure the change of color in diameter and one 8 x 11 piece of white paper will also be used for safety precautions. Methods First, a member of the group will gather all the materials including the Petri dishes filled with tap water and 2% agar, forceps, ruler, 8X11 piece of white paper and the jar that contains the potassium permanganate crystals, and bring the materials back to the designated area. Then the experimenter will start to conduct the experiment. Then the experiment will consist of placing the empty Petri dish and the agar Petri dish on top of the white paper side by side. Second, Tap water will be added to a half way point in the empty Petri dish until it is approximately the same level as agar in the other Petri dish. Before continuing, wait for the water to stop moving to get an accurate measure of the diffusion. After that, have lab partner assist with placing potassium permanganate crystals into the agar Petri dish, while at the same time, the primary experimenter places the other two potassium permanganate crystals into the tap water. Be sure not to splash water in the aqueous dish. The moment that each crystal has been lowered is Time Zero. A purple color will be obvious immediately. Next have the experiment observe the diffusion rate for every 3 minutes for the next 15 minutes. For every 3 minutes, measure the diameter of the diffusion circle in millimeters (mm) and write down the measurement on the chart given. Be careful not to disturb the aqueous Petri dish. Discussion The results show that there a major difference in the rate of diffusion between 2% agar and tap water. Immediately, when the potassium permanganate crystals were dropped at 0, there was already an instant diffusion of 2 mm, compared to agar which was 1mm. Because water is a polar molecule, diffusion across membranes travel quicker compared to a nonpolar substance like agar that diffuse though the lipid part of a membrane. At the first 3 minute mark, it shows that the crystals have diffused relatively fast at 15 mm, compared to the diameter in agar which has slowly diffused to 5 mm. for the next 12 minutes, results have show that the diameter in water has increase about 8 – 10 mm every 3 minutes and agar has stayed the same throughout. Due to passive transport, the movement of molecules from the potassium permanganate have a higher concentration, and are then added to water which diffuses from that high concentration to a lower concentration. This was the expected result. Since water is polar, the crystals can easily diffuse through the gradient. Furthermore, with agar being a nonpolar molecule, it maintained a state of dynamic equilibrium because it diffused slower but was diffused evenly. However since other factors do play a role in the rate of diffusion, maybe temperature could have changed the rate of diffusion for the two Petri dishes. Also had the allotted time been different there may have also been a change in the results. There were no negative results or errors made during this experiment. Based on the results it can be concluded that dropping potassium permanganate crystals into water, diffuses across the gradient faster compared to 2% agar. This does support the initial hypothesis and the predictions were accurate.
