Abstract
Public data including a prime number p, a natural number d, a matrix Q, and a matrix S are acquired by a public data acquisition section, and secret key including natural numbers n, kis generated by a shared secret key generation section. A matrix M(M=SQS) is calculated by a non-commutative matrix generation section and transmitted to a communication party, and a matrix M(M=SQS) is acquired from the communication party. A matrix M(M=SMSk) is computed as a common secret key by a shared secret key computation section. An encryption/decryption device is thereby capable of rapid generation of the secure common secret key.
