Threat Model and Defense Scheme for Side-Channel Attacks in Client-Side Deduplication

Side channel parameter characteristics of code injection attacks

Embedded systems are suggestive targets for code injection attacks in the recent years. Software protection mechanisms, and in general computers, are not usually applicable in embedded systems since they have limited resources like memory and process power. In this paper we investigate side channel characteristics of embedded systems and their applicability in code injection attack detection. T...

Algebraic Side-Channel Attacks

In 2002, algebraic attacks using overdefined systems of equations have been proposed as a potentially very powerful cryptanalysis technique against block ciphers. However, although a number of convincing experiments have been performed against certain reduced algorithms, it is not clear wether these attacks can be successfully applied in general and to a large class of ciphers. In this paper, w...

Channel Equalization for Side Channel Attacks

This paper introduces the use of channel equalization as a method of reducing the computational complexity of side channel analysis (SCA), by effectively collapsing all points in a power measurement trace into a single random variable. This uses a simple Finite Impulse Response (FIR) linear equalizer, which has been studied extensively in communications systems. In addition the estimation of a ...

Kangaroos in Side-Channel Attacks

Side-channel attacks are a powerful tool to discover the cryptographic secrets of a chip or other device but only too often do they require too many traces or leave too many possible keys to explore. In this paper we show that for side channel attacks on discrete-logarithmbased systems significantly more unknown bits can be handled by using Pollard’s kangaroo method: if b bits are unknown then ...
