SYSTOLIC PARALLEL GALOIS HASH COMPUTING DEVICE

A computing device (e.g., an FPGA or integrated circuit) processes an incoming packet comprising data to compute a Galois hash. The computing device includes a plurality of circuits, each circuit providing a respective result used to determine the Galois hash, and each circuit including: a first multiplier configured to receive a portion of the data; a first exclusive-OR gate configured to receive an output of the first multiplier as a first input, and to provide the respective result; and a second multiplier configured to receive an output of the first exclusive-OR gate, wherein the first exclusive-OR gate is further configured to receive an output of the second multiplier as a second input. In one embodiment, the computing device further comprises a second exclusive-OR gate configured to output the Galois hash, wherein each respective result is provided as an input to the second exclusive-OR gate.
