Abstract: A side channel attack utilizes information gained from the physical implementation of a cryptosystem. Software and hardware-based systems and methods for preventing side channel attacks are presented. Cryptographic hardware may introduce dummy operations to compensate for conditional math operations in certain functions such as modular exponentiation. Cryptographic hardware may also introduce random stalls of the data path to introduce alterations in the power profile for the operation. A cryptographic function may be mapped to a micro code sequence having a plurality of instructions. Firmware in the cryptosystem may alter the micro code sequence by altering the order of instructions, add dummy operations in the micro code sequence, break the micro code sequence into multiple sub micro code sequences and/or change the register location for source and destination operands used in the sequence. These alterations are designed to randomly change the timing and power profile of the requested function.

Abstract: Systems and methods for providing asymmetrical cryptographic acceleration are provided. The scalable asymmetric cryptographic accelerator engine uses a layered approach based on the collaboration of firmware and hardware to perform a specific cryptographic operation. Upon receipt of a request for a cryptographic function, the system accesses a sequence of operations required to perform the requested function. A micro code sequence is prepared for each hardware operation and sent to the hardware module. The micro code sequence includes a set of load instructions, a set of data processing instructions, and a set of unload instructions. An instruction may include a register operand having a register type and a register index. Upon receipt of a load instruction, the hardware module updates size information in a content addressable memory for a register included in the instruction. The hardware module continuously monitors the content addressable memory to avoid buffer overflow or underflow conditions.
