ABSTRACT:
In a network having a plurality of entities and a center, the center creates random numbers for all the combinations of two of the entities within the network, and delivers to each entity random numbers created for those combinations involving that entity. A sender entity selects a random number corresponding to the combination of that entity and the destination entity from a group of random numbers delivered to the sender entity, encrypts a communication text using an encryption key determined by the selected random number and sends the encrypted text to the destination entity. The destination entity selects a random number corresponding to the combination of itself and the sender entity from the random numbers delivered to the destination entity, and decodes a cipher text received using an encryption key determined by the selected random number.
