Abstract :
|
Side-channel attacks that use information leaked from a cryptographic module and fault attacks that inject disturbances are attracting great attention day by day. Thus it is in intense requirement to develop their countermeasures. Random delays are commonly used as a countermeasure to inhibit side channel analysis and fault attacks in embedded devices. Random delays in embedded software are seen which help to perform attack resilient cryptographic implementation. This paper shows some techniques of generating random delays and measuring the efficiency of random delay countermeasures.
