Abstract: An apparatus and method dynamically creates security keys for a subscriber, having at least one preexisting security credential set, and allows the configuration for N key pairs or N keys (where the cryptographic system is a symmetric key system). Such a system provides flexibility in assigning cryptographic algorithms and cryptographic keys to facilitate a change in algorithm without requiring reinitialization of a processing unit or subscriber. The apparatus and method provides a configurable security key manifest, such as a template or table, operative to contain a non-prespecified number of security keys. A security officer or other source may input key configuration data to a graphic user interface template or other suitable mechanism to configure the security key manifest.

Abstract: An apparatus and method provides arbitration among a plurality of subscribers and also provides access isolation between a requester, such as a subscriber or other entity, and a security-related information source, such as a repository containing certificates and certificate revocation lists (CRLs) or other security-related information. The system and method isolates the requester from the source by generating separate security information release-data to obtain the security-related information from the source based on analyzed request criteria-data. The arbitration module generates a separate security-information release request to the repository to retrieve appropriate data from the internal repository in response to the externally generated request without allowing the request to filter directly through to the security-related information source.

Abstract: A certificate issuing apparatus and method creates a new certificate of a differing format from an existing certificate format to facilitate certificate conversion. A certificate converting unit receives first certificate data in a first format and desired certificate format criteria data, such as data representing the format of a certificate to which the first certificate is to be converted. The apparatus and method then generates second certificate data in a second format in response to the desired certificate format criteria data. In one embodiment, this is done using certificate format template data, such as templates representing the format and/or syntax of a plurality of differing certificate formats. The format template data is then mapped so that information from one certificate can be suitably mapped and then placed in a proper format and syntax for a different certificate format.

Abstract: An application registration data generator, on a per application basis, generates application registration data that contains at least application identification data, such as, the name of a software application or a pathname to a software application, and stored unique application verification data that is based on executable file data. A data access determinator determines whether a calling application should be allowed access to the limited access based data by, for example, computing a hash value of the executable file and checking whether this hash value matches the corresponding stored unique application verification data. If there is a match, the application is granted access to the user's cryptographic parameters, privilege data, or other limited access based data on a per application basis.
