A new DNA strand-based encryption algorithm using symmetric key generation table

Hybrid encryption/decryption technique using new public key and symmetric key algorithm

This research study proposes Hybrid Encryption System using new public key algorithm and private key algorithm. A hybrid cryptosystem is one which combines the convenience of a public-key cryptosystem with the efficiency of a symmetrickey cryptosystem. Here, we propose a provably two way secured data encryption system, which addresses the concerns of user’s privacy, authentication and accuracy....

A DNA-Based Cryptographic Key Generation Algorithm

This paper presents a detail description of a new DNA-based cryptographic key generation algorithm that can be used to generate strong cryptographic key(s) for symmetric ciphering applications. The algorithm uses an initial private/secret key as an input to the Key-Based Random Permutation (KBRP) algorithm to generate a permutation of size n, which is half of the size of the required cryptograp...

A Symmetric Encryption Algorithm based on DNA Computing

Deoxyribo Nucleic Acid (DNA) computing is a new method of simulating the bimolecular structure of DNA and computing by means of molecular biology. DNA cryptography is a new field which has been explored worldwide. The concept of using DNA computing in the fields of cryptography and steganography has been identified as a possible technology, which may bring forward a new hope for unbreakable alg...

A New Fast Data Encryption Algorithm (FDE)

Strenthening Hash Functions using Block Symmetric Key Encryption Algorithm

With the requirement of high speed network protocols, fast message integrity and authentication services are at the top most priority. Currently many integrity techniques, that involve hashing, are being used and developed, but almost every technique faces one or other attack or any other security or performance related issue. The chief problem being faced is the forgery of hash value, being tr...
