  • Patent number: 11641285
    Abstract: Certificates issued by a CA are distributed across multiple CRLs. Each certificate issued by the CA is assigned to a specific CRL, and the address of that CRL is written to the appropriate field of the certificate, such that an authenticating application can subsequently determine if the certificate is revoked. When the CA revokes a specific one of the issued certificates, it determines to which CRL the revoked certificate is assigned, and updates the specific CRL accordingly. In some embodiments, a single one of the multiple CRLs is active for assignment of certificates at any given time, and each certificate issued by the CA is assigned to the currently active CRL. In other embodiments, assignments of issued certificates are distributed between different ones of a pre-determined number of multiple CRLs by applying a statistical distribution formula to each issued certificate to determine a corresponding target CRL.

  • Publication number: 20230054510
    Abstract: A container is disclosed. The container has a container body including a sidewall surrounding an interior void with opposite open ends. The sidewall retains a movable panel that moves in opposite longitudinal directions toward the opposite open ends to increase or decrease a storage volume. The movable panel may include a manual sealing and locking mechanism. The container also includes a cover that covers one of the open ends and is openable or removable for access to contents. A one-way valve in the cover, sidewall, or movable panel permits evacuation of excess air from the storage volume.

  • Patent number: 9692640
    Abstract: Techniques are disclosed for configuring a server to establish a secure network communication session. An application monitors one or more resource utilization metrics of the server. Upon determining that at least one of the monitored resource metrics satisfies a specified condition, an optimization algorithm is selected based on the resource metrics and a configuration of the server. The optimization algorithm determines an updated configuration of the server while maintaining the security at par or better. The selected optimization algorithm is performed to modify determine the updated configuration of the server. Once determined, the application applies the updated configuration to the server.

  • Patent number: 9300478
    Abstract: Techniques are disclosed for evenly distributing certificate status validity messages across multiple response servers. A certificate authority (CA) may partition subsets of online certificate status protocol (OCSP) responses to each be handled by OCSP response servers. The partitions are based on serial numbers of the underlying digital certificates of the OCSP responses. For example, to determine which OCSP response server is assigned to distribute a particular OCSP response, a modulo operation may be performed between the last octet value of the underlying certificate serial number and the total number of available OCSP response servers of the CA. The result yields a partition number that may be used to identify the corresponding OCSP response server.
