Abstract

A method and reconfigurable computer architecture protect binary opcode, or other data and instructions by providing an encryption capability integrated into an instruction issue unit of a protected processor. Opcodes are encrypted at their source, and encrypted opcodes from authorized users are then delivered to a CPU and decrypted “inside” the CPU. Access into the CPU is prevented. Each form of code or data selected for protection is protected from unauthorized viewing or access. Commonly, the binary executable, or object, code is selected for protection. However, protected information could also include source code or data sets or both. Encrypting opcodes will result in making unique opcodes for each processor. Encryption keys and hidden opcode algorithms provide further security.
