Encryption

privacy researcher at the American Civil Liberties Union, said “Yahoo and Google are taking early steps to making the technology easier for normal consumers.” It can be interpreted that few users will adopt the technology immediately. This paper explains what PGP encryption is and how it works, merit of PGP security, what makes difficulty of using PGP encryption, and its limitation. What is PGP encryption and how does it work? PGP is an abbreviation for “Pretty Good Privacy.” It is a hybrid encryption since PGP is a combination of some best features of both original and public key cryptography. If you encrypt the plaintext using PGP, it firstly compresses the plaintext and by data compression, modem transmission time and disk space are saved. Also, data compression strengthens cryptographic…

3rd Quarter Project Rough Draft What is encryption? Many of you may have heard it in a movie or on TV but never fully understand what it meant or it’s purpose. According to the American Heritage College Dictionary encryption means to encipher or encode information or an electronic device. Many tech companies install encryption software on devices to protect the user’s texts, emails, and general information. Your phone is encrypted if you have a password on it. The FBI and Police in many cities…

R. Buckminster Fuller once said “Humanity is acquiring all the right technology for all the wrong reasons.” ( The words of R. Buckminster Fuller are more relevant now than ever before; especially with the invention and use of dangerous technology such as encryption. Encryption works by using complex mathematical algorithms to scramble the contents of a file or message to another form, called ciphertext, which renders it unreadable to outside parties. Various encryption algorithms, many of which…

The article “Quantum Computer Comes Closer to Cracking RSA Encryption” written by Amy Nordrum, shows that Cryptography needs to be important, because of the fast developing of new technology. In her article Ms. Nordrum tells about computer scientists from the MIT which found a way to crack the RSA (Rivest, Shamir and Adleman)-Code. On the fact, that RSA Encryption is used in all our devices it is quite frightening to know that the government is maybe already using this kind of technology for…

2 DESCRIPTION OF THE USEA 2.1. Data Encryption phase USEA encrypts 512-bit blocks of plaintext to cipher text by a 256-bit main key that from now we call it MK. In default, USEA consists of 20 identical rounds, but we can increase or decrease the rounds for amplification of our algorithm in specific hardware or software implementation. Note that Decreasing rounds of algorithm reduces its security against attacks. USEA uses different algebratic, logic and arithmetic operations for data…

Abstract— the focus in this paper is on the symmetric encryption. There are some basic information about this type of cryptography will be reviewed. Then, symmetric cryptography advantages and problems will be covered. After that, comparison on several symmetric algorithms are discussed. These algorithms are DES, Triple DES, AES, RC2, RC4, RC6, and Blowfish. Keywords—Cryptography, Symmetric Encryption, Encryption, Decryption, DES, Triple DES, AES, RC2, RC4, RC6, Blowfish. I. INTRODUCTION…

The government thinks that digital things can be made so only they can access, but “When you build a fence around your house to keep out intruders you don’t leave a big hole in the fence for easy access to the police” ("Billions at stake"). The government is parasitically taking our privacy and always trying to take more from the people justifying that it is all in the name of national security. Mass surveillance is already put in place and now they want to ban encryption. The government 's…

Recently, a suspect in a Manhattan felony, speaking on a recorded jailhouse call, noted that “Apple and Google came out with these softwares” that the police cannot easily unlock. Apple, Google and other proponents of full-disk encryption have offered several rationales for this new encryption technology. They have portrayed the new policy as a response to the concerns raised by Edward J. Snowden about data collection by the National Security Agency. They say full-disk encryption makes devices…

you avoid common mistakes made with cryptographic software One action that a company can take to avoid some common mistakes made with cryptographic software is to avoid using their own encryption algorithms. When you have an in house cryptographic algorithm developer, it probably seems like a good idea to develop your own cryptographic algorithms. After all, how could you possibly break your own proprietary algorithm? Breaking an algorithm is easier than it looks,…

from unwanted intruders through transforming the information to a format that is unreadable. The people with the required authentication are the only ones can read or return the data to original form. It is a system dependant mainly on the usage of a key and the main basic principle of network security. Cryptography involves plain text, which is the text that someone will type in a form that is understandable to the human. This plain text will then undergo encryption, which is a technique that…
