Accelerating the secure remote password protocol using reconfigurable hardware

摘要: The Secure Remote Password (SRP) protocol is an authentication and key-exchange suitable for secure password verification session key generation over insecure communication channels. modular exponentiations involved, however, are very time-consuming, causing slow log-on procedures. This work presents the design of a hardware accelerator that performs exponentiation wide integers. experimental platform tutwlan, Wireless Local Area Network (wlan) being developed at Tampere University Technology. It runs on Altera Excalibur development board contains microprocessor chip with programmable hardware. results show full 1023-bit inputs can be performed in less than 40 ms using 10,000 logic elements, each consisting 4-input lookup table register. By implemented protocol, execution time reduced by factor 4. In addition, proposals to improve architecture presented. An additional 5 improvement (totaling 20) achieved implementing fastest design.
