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. Having done this, the secured communication device is then receptive to receiving access requests from a plurality of software applications. The access requests are each requesting that data created by a corresponding one of the plurality of software application be secured via the security application. In response to the request, the data is secured based on either the updated local security parameters or the existing local security parameters.
