Abstract:

. Cryptosystem designers frequently assume that secrets will be manipulated in closed, reliable computing environments. Unfortunately, actual computers and microchips leak information about the operations they process. This paper examines specific methods for analyzing power consumption measurements to find secret keys from tamper resistant devices. We also discuss approaches for building cryptosystems that can operate securely in existing hardware that leaks information. Keywords: differential power analysis, DPA, SPA, cryptanalysis, DES 1 Background Attacks that involvemultiple parts of a security system are difficult to predict and model. If cipher designers, software developers, and hardware engineers do not understand or review each other's work, security assumptions made at each level of a system's design may be incomplete or unrealistic. As a result, security faults often involveunanticipated interactions between components designed by different people. Manytechniques ...
