TL;DRAbstract
In Wireless Local Area Networks (wlans), data is transferred through the ether. To prevent that unauthorized users read or modify data, security is needed, not only to secure data transmission but also to authorize users and machines to the network. A secure log-on procedure can be created with the help of cryptographic functions. However, these functions are often computationally intensive which results in a slow log-on procedure. This work focuses on the design of the hardware acceleration of a wlan authentication proceduce. The hardware acceleration is used in the Secure Remote Password (srp) authentication protocol, but can be used in other security related computations as well. The experimental platform is tutwlan, a wlan platform being developed at Tampere University of Technology which runs on the Altera Excalibur development board that contains a chip with programmable hardware and a microprocessor.
