Abstract:
An embodiment of the present invention proposes a new secure microprocessor for software protection. The invention presents a secure microprocessor, which embeds a symmetric encryption/decryption hardware a symmetric key (Embedded Key), and a safe cache. The symmetric encryption/decryption is the same for all microprocessors, but the Embedded Key is unique for each microprocessor.
