, but are difficult and time-consuming to develop. The SHERIF architecture described in this paper seeks to provide a flexible cryptographic hardware platform targeted for 0.18 micron CMOS technology, capable of greater speeds than software implementation while allowing for an ease of implementation not found

We present a theoretical model for breaking various cryptographic schemes by taking advantage of random hardware faults. We show how to attack certain implementations of RSA and Rabin signatures. An implementation of RSA based on the Chinese Remainder Theorem can be broken using a single erroneous

The use of cryptographic hash functions like MD5 or SHA for message authentication has become a standard approach inmanyInternet applications and protocols. Though very easy to implement, these mechanisms are usually based on ad hoc techniques that lack a sound security analysis. We present new

modules. We demonstrate that for frequently communicating modules, implementing fault isolation in software rather than hard-ware can substantially improve end-to-end application performance.

We present Telos, an ultra low power wireless sensor module (“mote”) for research and experimentation. Telos is the latest in a line of motes developed by UC Berkeley to enable wireless sensor network (WSN) research. It is a new mote design built from scratch based on experiences with previous mote

the tradeoffs among different cryptographic primitives and use the inherent sensor network limitations to our advantage when choosing parameters to find a sweet spot for security, packet overhead, and resource requirements. TinySec is portable to a variety of hardware and radio platforms. Our experimental

. The instrumentation is controlled by the Performance Consultant module, that automatically directs the placement of instrumentation. The Performance Consultant has a well-defined notion of performance bottlenecks and program structure, so that it can associate bottlenecks with specific causes and specific parts of a

of its contents like today’s game consoles and cellular phones. The software stack in each VM can be tailored from the hardware interface up to meet the security requirements of its application(s). The hardware and TVMM can act as a trusted party to allow closed-box VMs to cryptographically identify

Abstract. This document describes the RC5 encryption algorithm. RC5 is a fast symmetric block cipher suitable for hardware or software implementations. A novel feature of RC5 is the heavy use of data-dependent rotations. RC5 has a variable word size, a variable number of rounds, and a variable

Program families are defined (analogously to hardware families) as sets of programs whose common properties are so extensive that it is advantageous to study thecommon properties of the programs before analyzing individual members. The assumption that, ifone is to develop a set of similar programs
