Data Encryption Using Bio Molecular Information

Data Encryption Using Bio Molecular Information

Cryptography is a field, which makes the transmitted message unreadable to unauthorised users. In this work we take inspiration from DNA encryption schemes and use of biological alphabets to manipulate information by employing the DNA sequence reaction, to autonomously make a copy of its threads as an extended encryption key. Information is converted from plain text to several formats and then ...

A New Fast Data Encryption Algorithm (FDE)

Fractional Bio-Image Encryption using Karhunen-Loeve Transform

Bio-images such as fingerprint, face and iris are sensitive and hence small change in such images could affect the result substantially. The processing overhead could be reduced by encrypting a preferred region instead of encrypting the entire image. In this paper a novel fractional bio-image encryption method is presented using Karhunen-Loeve (KL) transform, which is a reversible linear transf...

A Secure Iris Image Encryption Technique Using Bio-Chaotic Algorithm

Due to dramatic enhancement in computers and communications and due to huge use of electronic media, security gains more and more importance especially in those organizations where information is more critical and more important. The older techniques such as conventional cryptography use encryption keys, which are long bit strings and are very hard to memorize such a long random numbers. Also i...
