A Secure License Key Generation using FBPS

Secure message transmission is generally required for the system where transmitted message need to be verified at the receiver end. Fibonacci develops the reversible encryption algorithms as mentioned in below technique. The technique considers a message as binary string on which the Fibonacci Based Position Substitution (FBPS) method is applied. A block of n bits is taken as an input stream from a continuous stream of bits. The decimal equivalent value of a source block is obtain and finds its position on the Fibonacci series, on a number or in between two numbers. The source value is mapped on a previous number of the series called target number. For proper one-one mapping a scheme is applied on the target number. This target number is again projected on a previous number and so on until the target number reached in a 0 or 1. Each time of the projection a 0 or 1 is produced. Plain text is encrypted for different block sizes as per the specification of a session key of a session to generate the final encrypted stream. Comparison of the proposed technique with existing and industrially accepted RSA and Triple DES.
