Side-Channel Attacks on Quantum-Resistant Supersingular Isogeny Diffie-Hellman

In this paper, we present three side-channel attacks on the quantum-resistant supersingular isogeny Di e-Hellman (SIDH) key exchange protocol. These re ned power analysis attacks target the representation of a zero value in a physical implementation of SIDH to extract bits of the secret key. To understand the behavior of these zero-attacks on SIDH, we investigate the representation of zero in t...

Multiple-Differential Side-Channel Collision Attacks on AES

In this paper, two efficient multiple-differential methods to detect collisions in the presence of strong noise are proposed binary and ternary voting. After collisions have been detected, the cryptographic key can be recovered from these collisions using such recent cryptanalytic techniques as linear [1] and algebraic [2] collision attacks. We refer to this combination of the collision detecti...

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...
