Abstract(in English) | We propose group key distribution schemes with an efficient"terminal revocation", which renews a group key of all the terminals except a specific one. In such broadcast systems as pay TV, conference system and mobile telecommunication for a group, a quick terminal revocation is required to protect the secrecy of the group communication. To realize the quick terminal revocation when the group has many terminals, we propose the schemes of which the transmitted data amount and the time delay after identifying the revoked terminal do not depend on the number of the terminals. The difficulty of detecting the new group key for the revoked terminal is estimated as same as breaking RSA public key cryptosystems. |
