  • 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.

  • Patent number: 10470564
    Abstract: A support device adapted to support an electronic device is provided. The electronic device has a display surface. The support device includes a base, a support frame, and at least one torque fixing assembly. The base includes a first arc surface portion. The support frame includes a second arc surface portion opposite to the first arc surface portion and an axis. The support frame rotates along the axis such that the second arc surface portion slides relative to the first arc surface portion and the electronic device switches between a first use state and a second use state. The torque fixing assembly is disposed at the first arc surface portion and the second arc surface portion. When the second arc surface portion slides relative to the first arc surface portion, the second arc surface portion rubs against the torque fixing assembly and torque is generated.
