摘要： A method and system for hiding an encryption key. The method including creating a directed graph having a plurality of vertices and edges, including a source and a sink vertex. Each vertex has a vertex value. The source vertices have a common source value, and the sink vertices have a common sink value, the sink value being a function of the source value and the encryption key. Each edge has an edge value that is a function of r(in)−1 and r(out) where r(in)−1 is the functional inverse of the vertex value of the predecessor vertex and r(out) is the vertex value of the successor vertex. A message enters a source vertex; flows along a path from the source vertex to a sink vertex; and leaves the sink vertex, where the output message is an encrypted or decrypted version of the input message using the private encryption key.

摘要： A software system that transforms an original application into an STPM enabled application and runs the enabled application. At protect time, an anti-tamper tool accepts the original application, uses anti-tamper techniques to create a guarded application, creates a security wrapper according to a policy file, and wraps the guarded application to create the STPM enabled application. A trusted service provider is inserted at the entry point of the enabled application. A set of core services is made accessible to the enabled application through the trusted service provider. At runtime the trusted service provider creates a TSP thread and passes a security file to an STPM device driver implementing TPM functionality and protected by anti-tamper techniques. The TSP thread actively monitors the enabled application and interacts with the STPM device driver through the set of core services.
