Abstract: An application processor includes a security processor. An operating method of the security processor includes generating a recoder input including a digit-unit multiplier and a reference bit. At least one random bits having a random value are generated. When the recoder input has a predetermined pattern, the recoder input is converted into a first recoding value or a second recoding value according to a random bit corresponding to the recoder input to generate a recoding result.

Abstract: A security device includes a secure processor, a mail box, a cryptographic intellectual property (IP), a secure direct memory access (DMA) circuit, and an internal memory. The secure processor provides an isolated execution environment. The mail box transfers a request from a CPU to the secure processor. The cryptographic IP performs one or more secure operations, including a signature certification operation, an encryption/decryption operation, and an integrity verification operation, on secure data within the isolated execution environment and without intervention of the CPU. The secure DMA circuit controls the one or more secure operations within the isolated execution environment, wherein only the secure processor is configured to control the secure DMA circuit. The internal memory stores the secure data on which the one or more secure operations are performed. The cryptographic IP includes a DMA circuit configured to control data access to an external storage.
