Patent ID: 7822208

Claim:
A method for creating and managing symmetrical cryptographic keys, wherein a symmetrical cryptographic key can be used to both encode and decode data, and wherein each key is intended for a user managed by a computer system comprising: searching in storage means for at least one user for which a symmetric key must be created, each user associated with one or more attributes comprising a status attribute and a scheduling attribute, wherein said status attribute is capable of having any one of the following values: pending, in progress, process ended with an error message, process done, sending a creation request and done; creating, based on said one or more attributes, at least one individual creation request for creating a symmetric key for said user, said creating further comprising periodically executing said individual creation request based on said scheduling attribute; transmitting a key generating request corresponding to said individual creation request to a key generating center; issuing, by said key generating center, a symmetric key in accordance with said transmitted key generating request; and creating each of said individual creation requests from a corresponding multiple creation request recorded in the storage means relative to a set of users belonging to a preset list, or to a set of users defined by predetermined criteria, as well as relative to model pairs of keys for either of said sets of users.
