DNA AND DNA COMPUTING IN SECURITY
Abstract
As modern encryption algorithms are broken, the world of information security looks in new directions to protect the data it transmits. The concept of using DNA computing in the fields of cryptography and steganography has been identified as a possible technology that may bring forward a new hope for unbreakable algorithms. Is the fledgling field of DNA computing the next cornerstone in the world of information security or is our time better spent following other paths for our data enc ....etc

Abstract
This paper discusses reduction of the number of product terms in representation of totally symmetric Boolean functions by Sum of Products (SOP) and Fixed Polarity Reed- Muller (FPRM) expansions. The suggested method reduces the number of product terms, correspondingly, the implementation cost of symmetric functions based on these expressions by exploiting Gray decoding of input variables. Although this decoding is a particular example of all possible linear transformation of Boolean variables, it is efficient in the case of sym ....etc

five models of symmetric key algorithm

Give a detail Compative study of all five models of symmetric key algorithm?
Ans. Secret Key Cryptography
With secret key cryptography, a single key is used for both encryption and decryption. the sender uses the key (or some set of rules) to encrypt the plaintext and sends the ciphertext to the receiver. The receiver applies the same key (or ruleset) to decrypt the message and recover the plaintext. Because a single key is used for both functions, secret key cryptography i ....etc
