Disclosed is a new and flexible approach for managing physical security in an electronic lock-and-key system. The novel approach does away with cabling or other direct connecting between locks (2) and a system management center. The (physical) keys (3) serve to disseminate access control and other information within the system in a snowball-like way, using an adapted, but simple networking protocol. Whenever appropriate, cryptographic schemes are applied to protect the system.
La présente invention concerne une nouvelle approche souple de gestion de la sécurité physique dans un système électronique à serrures et clés. Cette nouvelle approche supprime le câblage ou toute autre connexion directe entre des serrures (2) et un centre de gestion de système. Les clés (3) (physiques) servent à disséminer les informations de commande d'accès et d'autres informations dans le système selon un effet boule de neige, à l'aide d'un protocole de réseau adapté mais simple. Au besoin, des programmes cryptographiques sont appliqués pour protéger le système.
