A Polymorphic Advanced Encryption Standard – A Novel Approach

To secure various forms of data, a polymorphic variant the Advanced Encryption Standard (P-AES) has been introduced. In P-AES, AES parameters' values will change with every new key. The exact be available only to legitimate communicating parties during execution time. achieve these objectives, basic transformations, SubBytes, ShiftRows, and MixColumns, have made key-dependent in proposed P-AES. Hence, key, transformations operate differently. receiver can retrieve operations' details from encryption Consequently, polymorphism achieved interoperability remains intact. P-AES implemented seamlessly using existing modules, performance was more or less equal (71 70 milliseconds encrypt 500 bytes respectively). From security standpoint, fully complies Kerckhoff's principle. This means cipher an open design, provided by depends on secrecy resistance differential linear attacks proved. Moreover, resulting 128 different ways, which significantly reduce capabilities any sophisticated attacker. Furthermore, P-AES's scores key avalanche plaintext were 0.496 0.504 respectively. Finally, Statistical Test Suite (STS) recommended NIST used ensure randomness output, passed all STS tests.
