Abstract: A storage device with improved security performance is provided. The storage device comprises a first non-volatile memory storing a firmware image, a second non-volatile memory storing an emergency image, and a storage controller controlling the first and second non-volatile memories, wherein the storage controller checks an integrity of the firmware image received from the first non-volatile memory, loads and executes the emergency image from the second non-volatile memory when the integrity check of the firmware image fails, receives a recover image from an external device based on the emergency image, and provides the recover image to the first non-volatile memory.

Abstract: An electronic circuit includes an operator including logic gates configured to perform either one or both of encryption and decryption operations. The electronic circuit further includes a controller configured to control the operator to operate in a first mode in which each of the logic gates outputs a first logic value during a first time period of a clock signal, and operate in a second mode in which a number of first logic gates, each of which outputs the first logic value, among the logic gates, and a number of second logic gates, each of which outputs a second logic value, among the logic gates, are maintained constant during a second time period of the clock signal, in response to a control value indicating that either one or both of the encryption and decryption operations are performed.

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.
