topic‚ and have been discussed in detail. The other terms that are crucial related to this topic is Secret Keys and Ciphers (upon which our entire report is based). ENCRYPTION AND DECRYPTION As said earlier‚ Encryption and Decryption are the two most basic terms of Cryptography. Here‚ the secret is to convert the plain text‚ which is the usual text that we encounter daily‚ into a Cipher text which on sight looks just like a ordinary plain text but with a secret message hidden which can be only read

Methods There are two standard methods of cryptography‚ asymmetric encryption and symmetric encryption. Data that is in its original form (unscrambled) is called plaintext. Once the data is scrambled and in its encrypted form it is called cipher text. The cipher text‚ which should be unintelligible to anyone not holding the encryption key‚ is what is stored in the database or transmitted down the communication line. Asymmetric encryption (also know as public key encryption) uses two separate keys

Comparison Chart BASIS FOR COMPARISON DES (DATA ENCRYPTION STANDARD) AES (ADVANCED ENCRYPTION STANDARD) Basic In DES the data block is divided into two halves. In AES the entire data block is processed as a single matrix. Principle DES work on Feistel Cipher structure. AES works on Substitution and Permutation Principle. Plaintext Plaintext is of 64 bits Plaintext can be of 128‚192‚ or 256 bits Key size DES in comparison to AES has smaller key size. AES has larger key size as

AES is a symmetrical encryption standard. The Advanced Encryption Standard‚ or AES is a specification for the encryption of electronic data established by the U.S. National Institute of standards and technology in 2001. It is based on the Rijndael cipher‚ and was developed by two Belgian cryptographers‚ Joan Daemen and Vincent Rijmen . AES is based in a design principlae known as a substitution-permutation network‚ and is fast both in software and hardware (Schneier). Unlike its predecessor DES‚

Considering digital image features with high volumes and video data‚ especially in real-time applications‚ the use of classic encryption methods like DES‚ AES‚ ...‚ is not efficient in terms of being time cosuming. In this article‚ a new method is proposed to encrypt digital images‚ using chos systems and utilizing DNA patterns. A central idea in the method suggested is to produce a pseudo-random DNA strand using chaos functions‚ which an encrypted strand is created‚ using the random strand and the

Before S/MIME‚ administrators used a widely accepted e-mail protocol to transfer messages‚ Simple Mail Transfer Protocol (SMTP)‚ which was inherently less secure. With S/MIME‚ administrators now have an e-mail option that helps provide greater security than SMTP‚ enabling widespread and secure e-mail connectivity. S/MIME provides two security services: •Digital signatures
