摘要
A system for generating a cryptographic key (k) shared by entities (A, B) that establish communications, which is particularly called a key predistribution system. A center algorithm (G) which the center only knows is formed under the conditions determined among a plurality of entities that establish communications under the control of the center, and discriminators (yA, yB) of the entities (A, B) are adapted to the center algorithm to form secret algorithms (XA, XB) specific to each of the entities. Then the secret algorithms are loaded onto cipher forming means (2, 3) such as IC cards. The cipher forming means (2, 3) are mounted on the individual entities (A, B), and the discriminators (yB, yA) of the other entities are applied to each other to calculate the cryptographic key (k), thereby forming the shared cryptographic key. The invention further discloses a system of communications using the above-mentioned shared cryptographic key.
