Information security is essential nowadays. Large number of cipher generation and decryption algorithms exists and are being evolved due to increasing demand of users and e-commerce services. In this paper we propose a new approach for secure information transmission over communication channel with key variability concept in symmetric key algorithms using Fibonacci Qmatrix. Proposed approach will not only enhance the security of information but also saves computation time and reduces power requirements that will find it’s suitability for future hand held devices and online transaction processing.
