Security Algorithms for Highly Constrained Devices such as RFIDTags

RFID tags are tiny computational devices with no internal source of power, which are likely to be deployed in a large number of applications in the next few years. In this talk I will describe several light weight security algorithms which were designed specifically for such devices, and in particular a new hash function called SQUASH which is provably at least as one-way as the Rabin scheme. It can be implemented with a very small number of gates on RFID tags, and it is extremely fast on larger processors with arbitrary word sizes.
