Abstract
A data encryption-decryption method for enhancing the confidentiality of data transmitted between two, first and second communication network entities including the steps of: at the first network entity, performing a quadruple-churning operation on a byte N to obtain an encrypted byte N, the quadruple-churning operation including: performing a first churning operation to obtain a first churned output; bit-wise XORing the first churned output with two values to obtain a first XOR result; bit-swapping the first XOR result; performing a second churning and XORing stages to obtain a second XOR result; performing a third churning and XORing stages to obtain a third XOR result; bit swapping the third XOR result; and performing a fourth churning operation on the third bit-swapped XOR result to obtain encrypted byte N; and transmitting the encrypted byte N to the second network entity.
