摘要: The substitution boxes are used in block ciphers with the purpose to induce confusion data. design of a box determines ability cipher; therefore, many different types have been proposed by various authors literature. In this paper, we present novel method new and compare its characteristics some prevailing cryptography. algorithm paper apply action projective linear group PGL(2, GF(28)) on Galois field GF(28). corresponds particular type fractional transformation (35z + 15)/(9z 5). order test strength box, non-linearity test, bit independence criterion, approximation probability method, differential strict avalanche majority logic criterion. This technique synthesize offers powerful algebraic complexity while keeping software/hardware within manageable parameters.
