An apparatus and method for providing a security service are provided. The apparatus for providing a security service includes a first block cipher and a second block cipher. The second block cipher is independent of the first block cipher, and is configured to be used as a random number generator when the first block cipher is used to perform encryption/decryption, and to be used to perform encryption/decryption when the first block cipher is used as a random number generator.

Apparatus and method for providing security service

An apparatus for protecting against external attacks for a processor based on an ARM core and a method using the same are provided. A method for protecting against external attacks for a processor based on an ARM core in accordance with an embodiment of the present invention includes: setting up a register using a reset handler, which is executed first within a boot image; generating a control signal for protecting against external attacks using any one of an external debug request signal and an output signal of the register; and blocking a JTAG interface used for JTAG communication with the processor based on the ARM core according to the control signal for protecting against external attacks.
