Abstract

See full text

Systems and methods for enhanced security of media are provided. Media security may be enhanced by improving the setup of encryption and/or decryption, by improving the performance of encryption and/or decryption, or by improving both. The calls related to enhanced security of media from an application in an emulated environment to a security module in the operating system hosting the emulated environment may be combined to reduce the overhead of accessing a security module. An application handling secure shell (SSH) communications may execute multiple calls to a cryptographic module in the host operating system. Because many calls to the cryptographic module during SSH communications follow patterns, two or more related calls may be combined into a single combined call to the cryptographic module. For example, a call to generate a server-to-client key and a call to generate a client-to-server key may be combined into a single call.
