Abstract:
1. A method for managing lists of rights of access between subjects and objects, stored in a data processing means from an external administrator entity comprising the following steps: initially associating keys of administrator entities with access rights lists and storing a security algorithm in the data processing means, and subsequently accessing an access rights list from the entity by: signing the access rights list in the entity by applying determined data from the list and an associated key to the security algorithm in order to produce a signature, transmitting the signature from the entity to the data processing means, comparing the signature received in the data processing means with determined signatures according to applications of determined data in lists of access rights contained in the data processing means and of keys respectively associated with these lists to the security algorithm, and allowing access of the entity to an access rights list only if its determined signature is identical to the received signature.
