  • Patent number: 8898451
    Abstract: A method for efficiently decrypting asymmetric SSL pre-master keys is divided into a key agent component that runs in user mode, and an SSL driver running in kernel mode. The key agent can take advantage of multiple threads for decoding keys in a multi-processor environment, while the SSL driver handles the task of symmetric decryption of the SSL encrypted data stream. The method is of advantage in applications such as firewalls with deep packet inspection in which all encrypted data traffic passing through the firewall must be decrypted for inspection.

  • Patent number: 6055636
    Abstract: A method and apparatus for centralizing the processing of key and certificate life-cycle management is accomplished when security activation of a communication device has been detected. Security activation may occur at log-on of the secure communication device (e.g., a personal computer equipped with a security application, or applications), at activation of a security application, or at re-authentication of a security application. Once the security activation has been detected, the secured communication device accesses a depository of security information to retrieve relevant security information. The secured communication device then interprets the relevant security information to determine when local security parameters are to be changed. When local security parameters (e.g., encryption key pair, a corresponding encryption public key certificate, a signing key pair, and/or a corresponding verification public key certificate) are to be changed, the local security parameters are updated.
