VLSI design methods for low power embedded encryption

摘要

Intelligent things, medical devices, vehicles and factories, all part of cyberphysical systems, will only be secure if we can build devices that can perform the mathematically demanding cryptographic operations in an efficient way. Unfortunately, many of devices operate under extremely limited power, energy and area constraints. Yet we expect that they can execute, often in real-time, the symmetric key, public key and/or hash functions needed for the application. At the same time, we request that the implementations are also secure against a wide range of physical attacks. This presentation will focus on the design methods to realize cryptographic operations on resource constrained devices. To reach the extremely low power, low energy and area budgets, we need to consider in an integrated way the protocols, the algorithms, the architectures and the circuit aspects of the application. These concepts will be illustrated with the design of several cryptographic co-processors suitable for implementation in embedded context.
