Abstract
A computer enabled method and apparatus for encrypting and decrypting data using a keyless transformation cryptographic technique. Data is protected using a keyless (unkeyed) complex mathematical transformation, in contrast to a traditional cryptographic algorithm using a secret key. This approach is resistant to both static analysis (hacking) performed on executable encryption/decryption code, as well as dynamic analysis performed during execution (runtime) of ciphering or deciphering. The method uses a family of asymmetric data transformations based on Galois field polynomials.
