DNA and Blum Blum Shub Random Number Generator Based Security Key Generation Algorithm

The communication sector suffers from serious security related threats. The technique presented in this paper is a step towards providing security to the confidential data. The work is based on generating a unique key through DNA and random number generator. Each random sequence produced by Blum Blum Shub random number generator is the result of a seed value which makes the sequence unique and reproducible. The final security key obtained is unique and upon being tested using NIST randomness evaluation tests, it is concluded that the key generated retains its uniqueness to a high level, thus providing efficient security mechanism. Thus, it is possible to integrate it with any security system used in communication sector.
