Instruction set encryption

Instruction Set Encryption (ISE) is a technology that encrypts a computer instruction set to protect program code and data. Its main purpose is to improve the security of the system and resist at- tacks such as code tampering and code injection. As a high security feature of the chip instructions, cryptographic security that guarantees the absolute safety of the chip owner or miner, the computa- tion energy chip is also equipped with the basic instruction set encryption technology. In systems that use instruction set encryption, the processor uses a key to encrypt and decrypt the CPU instructions. The encrypted instruction set is stored in memory or on disk, and the decryptor is responsi- ble for decrypting the encrypted instructions and passing them to the CPU for execution. It is im- portant to note here that only authorized decryptors can decrypt and execute the encrypted instructions, and non-authorized decryptors cannot execute the encrypted instructions, thus protecting the security and integrity of the program and data. Instruc- tion set encryption is usually used in systems with highly secure requirements, such as financial trans- actions, military equipment, smart cards, etc. The advantage of instruction set encryption over tradi- tional software encryption is its ability to protect code and data at runtime, making it more difficult to be cracked by attackers. In the future, instruction set encryption will also play an important role in protecting data and core digital assets, etc. in our future Utility mining or AI training services.
