Abstract
A cryptographic rejection sampling unit includes n parallel rejection bounded sampling circuits coupled to receive n, four-bit samples in a cycle from a buffer containing a random bit string, where n is an integer having a value of at least 8. A first in-first out queue is coupled to receive valid output from the rejection bounded circuits. A multiplexer is coupled to the queue and configured to provide four valid coefficients in the cycle. A controller is coupled to control valid output provided from the queue to the multiplexer, to track a number of valid outputs in the queue, and to control the multiplexer to output the four valid coefficients. A method uses the cryptographic rejection sampling unit to generate and write the valid coefficients to a memory.
