摘要： The invention can achieve a recovery time that satisfies the demands of real-time transmission processing by performing, in an extremely short time period, an RSTP process in a network, which is configured in a ring topology and wherein a plurality of IEEE 802.3 compliant nodes is connected via prescribed transmission lines, using hardware to execute processes related to the physical layer and the data link layer of the OSI reference model—without software processing. The RSTP processing unit of each node: receives BPDU data, which is received from the network by one of two PHY units and stored in a BPDU send/receive buffer of a corresponding MAC unit that is connected to that PHY unit, via a BPDU data bus that is connected to that MAC unit; decodes the received BPDU data; performs a prescribed process; transfers the BPDU data, via the BPDU data bus that is connected to the other MAC unit, to the other BPDU send/receive buffer; and transmits that BPDU data from the PHY unit connected to the other MAC unit to the network.

摘要： A system and method for retrieving certificate of trust information for a certificate validation process. Fetching servers periodically retrieve certificate revocation lists (CRLs) from servers maintained by various certificate issuers. The revoked certificate data included in the retrieved CRLs are stored in a central database. An authentication server receives a request from a client for access to a secure service and initiates a validation process. The authentication server retrieves revoked certificate data from the central database and compares the retrieved revoked certificate data to certificate of trust information received from the client along with the request. The authentication server denies access to the secure information if the certificate of trust information matches revoked certificate data from the central database, allows access if the certificate of trust information does not match revoked certificate data from the central database.
