  • Pgp Encryption Research Paper

    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…

  • The Dangers Of Cryptography And Encryption

    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…

  • Closer To Cracking Rsa Encryption, By Amy Nordrum

    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…

  • Symmetric Encryption Vs Blowfish Algorithm

    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 Pros And Cons Of Mass Surveillance

    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…

  • Argumentative Essay On Apple's Ios 8 Operating System

    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…

  • Why Cryptographic Software Fail

    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,…

  • Basic Importance Of Cryptography

    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…

  • Bilinear Complexity Assumptions

    Diffie-Hellman (DDH) problem: We say that the decisional Diffie-Hellman (DDH) problem is hard if, for any PPT distinguisher A, the function |Pr⁡[A(G_1,q,g,g^a,g^b,g^c )=1]-Pr⁡[A(G_1,q,g,g^a,g^b,g^ab )=1]|, is negligible. 2.2. Outline of the Conjunctive Keyword Searchable Encryption [16] A conjunctive keyword searchable encryption (CKSE) consists of the following four algorithms: KeyGen(1^k): It is run by the senders to initiate the scheme. It takes a security parameter k, and returns a secret…

  • Analysis Of Government Surveillance By Edward Snowden

    surveillance occurs at all. The purpose of this project is to make people aware of surveillance and to show them the harmful effects that surveillance can have. In order to do that, I have to provide some background. First, I need to explain encryption. Encryption is a fundamental part of today’s technology. It allows for secure exchange of data between two or more parties. Every time you buy something online or log in to your Facebook account, encryption keeps your credit card details and…
