5 AES Contest: Encryption time in clock cycles on various platforms Twofish team: Bruce Schneier & Doug Whiting better

6 6 eBACS: ECRYPT Benchmarking of Cryptographic Systems 6 measurements on multiple machines (currently over 70) each implementation is recompiled multiple times (currently over 1200 times) with various compiler options time measured in clock cycles/byte for multiple input/output sizes median, lower quartile (25 th percentile), and upper quartile (75 th percentile) reported standardized function arguments (common API) SUPERCOP - toolkit developed by D. Bernstein and T. Lange for measuring performance of cryptographic software See http://bench.cr.yp.to/

7 7 1.Low Area Implementations of Two Selected SHA-3 Candidates and Comparison of Your Implementations with Implementations from Other Groups 2.Use of Embedded FPGA Resources (BRAMs, DSP units, etc.) in Implementations of 14 SHA-3 Candidates 3. Your ECE 545 project + extension discussed with the Instructor Hardware Projects

8 8 1.Optimizing Best Available Software Implementations of the SHA-3 candidates (using coding techniques, special instructions, assembly language, etc.). See http://bench.cr.yp.to/ 2.Comparing the sphlib 2.1 C (or Java) Implementations of Hash Functions with the Best C (or Java) Implementations Submitted to eBACS. See http://www.saphir2.com/sphlib/ http://bench.cr.yp.to/ 3. Porting Selected C Implementations of the SHA-3 Candidates to the TI MSP430 microcontroller or Other Microcontroller Available to You.
