Abstract
Distributed module authentication allows security checks to be initiated by multiple software modules. Module authentication processes can be inserted into two or more modules in an operating system and/or various other applications. These module authentication processes can verify the integrity of binaries associated with one or more modules in computer memory. Security checks can be performed on modules stored on disk, in active system memory, or in any other location. Various security checks can be coordinated with each other to ensure variety and frequency of module authentication, as well as to randomize the module authentication process that performs a particular security check. In addition, security processor code can be interleaved within normal application code, so the security code is difficult for attackers to remove or disable without damaging the useful functionality of an application.
