Abstract
A configurable sponge function engine. The configurable engine includes a register having bitrate and capacity sections, each having a variable size, where a sum of the bitrate and capacity sizes is fixed. A controller generates a bitrate size indication. A configurable message processor receives an input message from an input bus, receives the size indication, fragments the input message into fragmented blocks of a size specified by the size indication, and converts the blocks to a bus width of the bitrate and capacity sizes. An iterative calculator receives the blocks, performs iterative processing operations on the blocks, and stores a result of each operation in the register overwriting a previous register value. An output adaptor receives a value stored in the register after the block corresponding to the end of the input message is processed and outputs the register value converted to have an output bus width.
