Generally, the present disclosure provides technology modifying a first cryptographic cipher with one or more operations of a second cryptographic cipher. In some embodiments the technology leverages a mathematical relationship between representations of data used in the first and second ciphers to enable the substitution of one or more operations of the first cipher with one or more operations of the second cipher. The resulting modified cipher may in some instances exhibit improved performance and or security, relative to the unmodified first cipher. Methods, computer readable media, and apparatus including or utilizing the technologies are also described.
