In this paper, a novel encryption algorithm is proposed i.e. FPSKEA (proposed algorithm) which is a shared-key block cipher, with a block size of 128 bits. It is designed to meet and exceed the requirements for a standard for shared-key encryption in the next few decades. The main theme behind the design of FPSKEA is to get the best security/performance tradeoff by utilizing the strongest tools and techniques available today for designing block ciphers. As a result, FPSKEA provides a very high level of security, combined with much better performance than other existing ciphers.
