Abstract

Systems, methods, and apparatus are provided for policy protected cryptographic Application Programming Interfaces (APIs) that are deployed in secure memory. One embodiment is a method of software execution. The method includes executing an application in a first secure memory partition; formatting a request to comply with a pre-defined secure communication protocol; transmitting the request from the application to a cryptographic application programming interface (API) of the application, the API being in a second secure memory partition that is separate and secure from the first secure memory partition; and verifying, in the second secure memory partition, that the request complies with a security policy before executing the request.
