    Abstract: A method of encoding and an encoder are provided. The method includes generating first one-hot bits for most significant bits (MSBs) and second one-hot bits for least significant bits (LSBs) using input one-hot bits; encoding the first one-hot bits to the MSBs and complementary MSBs through a first logical operation using a cross-connection; and encoding the second one-hot bits to the LSBs and complementary LSBs through a second logical operation using a cross-connection. The encoder includes a first bit generator, a first encoder, a second bit generator and a second encoder.

    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.
