摘要： The present invention is directed towards systems and methods for determining a status of a client certificate from a plurality of responses for an Online Certificate Status Protocol (OCSP) request. An intermediary device between a plurality of clients and one or more servers identifies a plurality of OCSP responders for determining a status of a client certificate responsive to receiving the client certificate from a client during a Secure Socket Layer (SSL) handshake. Each of the plurality of OCSP responders may transmit a request for the status of the client certificate to a uniform resource locator corresponding to each OCSP responder. The intermediary device may determine a single status for the client certificate from a plurality of statuses of the client certificate received via responses from each uniform resource locator.

摘要： The present invention is directed towards systems and methods for managing SSL session persistence and reuse in a multi-core system. A first core may indicate that an SSL session established by the first core is non-resumable. Responsive to the indication, the core may set an indicator at a location in memory accessible by each core of the multi-core system, the indicator indicating that the SSL session is non-resumable. A second core of the multi-core system may receive a request to reuse the SSL session. The request may include a session identifier of the SSL session. In addition, the session identifier may identify the first core as an establisher of the SSL session. The second core can identify from encoding of the session identifier whether the second core is not the establisher of the SSL session. Responsive to the identification, the second core may determine whether to resume the SSL session.

摘要： The present invention is directed towards systems and methods for batching OCSP requests and caching corresponding responses. An intermediary between a plurality of clients and one or more servers receives a first client certificate during a first SSL handshake with a first client and a second client certificate during a second SSL handshake with a second client. The intermediary may identify that the statuses of the client certificates are not in a cache of the intermediary. An OCSP responder of the intermediary may transmit a single request to an OCSP server to determine the statuses. The intermediary may determine, from a single response received from the OCSP server, whether to establish SSL connections with the clients based on the statuses. The intermediary may store the statuses to the cache for determining whether to establish a SSL connection in response to receiving a client certificate from the first client.

摘要： The present invention is directed towards systems and methods for maintaining Certificate Revocation Lists (CRLs) for client access in a multi-core system. A first core may generate a secondary CRL corresponding to a master CRL maintained by the first core. The CRLs may identify certificates to revoke. The first core can store the secondary CRL to a memory element accessible by the cores. A second core may receive a request to validate a certificate. The second core can provisionally determine, via access to the secondary CRL, whether the certificate is revoked. The second core may also determine not to revoke the certificate. Responsive to the determination, the second core may request the first core to validate the certificate. The first core can determine whether to revoke the certificate based on the master CRL. The first core may send a message to the second core based on the determination.
