Hardware Evaluation of the Stream Cipher-based Hash Functions RadioGatun and irRUPT
In the next years, new hash function candidates will replace the old MD5 and SHA-1 standards and the current SHA-2 family. The hash algorithms RadioGatun and ir-RUPT are potential successors based on a stream structure, which allows the achievement of high throughputs (particularly with long input messages) with minimal area occupation. In this paper, several hardware architectures of the two above mentioned hash algorithms have been investigated. The implementation on ASIC of RadioGatun with a word length of 64 bits shows a complexity of 46 k Gate Equivalents (GE) and reaches 5.7 Gbps throughput with a 3 64- bit input message.
