Cipher Instruction Search Attack on the Bus-Encryption Security Microcontroller DS5002FP

Abstract—A widely used bus-encryption microprocessor is vulnerable to a new practical attack. This type of processor decrypts onthe-fly while fetching code and data, which are stored in RAM only in encrypted form. The attack allows easy, unauthorized access to the decrypted memory content.
