The Fundamentals of a SHA-256 Master/Slave Authentication System


Abstract: Maxim’s DeepCover® Secure Authenticators (DS2465, DS28E15, DS28E22, DS28E25) implement advanced physical security to provide the ultimate in low-cost IP protection, clone prevention, and peripheral authentication. This application note first introduces the authenticators and the coprocessor with their specific characteristics and commands. Then it explains the general logistics of the SHA-256-based security system. Finally, it illustrates the use of an authenticator and a coprocessor to perform mutual authentication of the master and the slave in a real application.
