Patent

CA 2159159

ELT transformation circuits 101l to 10m are preliminarily supplied with ELT transformation parameters a i, b i, and p i (i = 1, 2, ..., m). When a plaintext of n bits long is supplied to the ELT transformation circuit 101l via an input terminal 104, the ELT transformation circuit 101l carries out ELT transformation on the plaintext by the use of ELT transformation parameters a l, b l, and p l supplied from an input terminal 105l. An enciphering circuit 102l enciphers an n/2-bit input with reference to a cryptographic key K l from an input terminal 106l. Supplied with two n-bit inputs, an exclusive-OR circuit 103l carries out an exclusive-OR operation between every corresponding bits of the same order. Subsequently, similar operation as mentioned above is repeated. The ELT transformation circuit 101m at a final stage delivers a ciphertext to an output terminal 107.
