title: A New Design of Permutation Function Using Spiral Fibonacci in Block Cipher
abstract: Cryptography is an important part of information security that covers the investigation of algorithms and protocols for secure information. With the advance of technology, a new design of cryptographic algorithm is required to fulfil the new system requirements. This paper emphasizes on the new design of permutation function for improving security in modern block ciphers. The Spiral Fibonacci method is designed to rearrange or permute inputs of bits through the substitution boxes. Then, the expe
