ABSTRACT:
An encryption communication system including: a communication center having at least a key information generating unit for generating key generating information used for encryption communication; and a plurality of user computers, each interconnected by a plurality of paths through the communication center, and each having at least an encryption key generating unit and an encryption processing unit. The communication center generates the key generating information Z based on predetermined modulo arithmetic formula. The user computer sends a password PW to the communication center, receives the key generating information therefrom, and generates an encryption key K used between the user computer and another party's computer based on predetermined modulo arithmetic formula. Further, the communication center provides a plurality of modulus numbers to share prime numbers assigned to at least two paths between the user computer and the other party's computer, and between the user computer and another party's computer, so that is possible to reduce the number of prime numbers.
