Linear Repairing Codes and Side-Channel Attacks

Linear Repairing Codes and Side-Channel Attacks

To strengthen the resistance of countermeasures based on secret sharing, several works have suggested to use the scheme introduced by Shamir in 1978, which proposes to use the evaluation of a random ddegree polynomial into n > d+1 public points to share the sensitive data. Applying the same principles used against the classical Boolean sharing, all these works have assumed that the most efficie...

Side-channel attacks based on linear approximations

Power analysis attacks against embedded secret key cryptosystems are widely studied since the seminal paper of Paul C. Kocher, Joshua Jaffe and Benjamin Jun in 1998 where has been introduced the powerful Differential Power Analysis. The strength of DPA is such that it became necessary to develop sound and efficient countermeasures. Nowadays embedded cryptographic primitives usually integrate on...

Complementary Dual Codes for Counter-Measures to Side-Channel Attacks

We recall why linear codes with complementary duals (LCD codes) play a role in counter-measures to passive and active side-channel analyses on embedded cryptosystems. The rate and the minimum distance of such LCD codes must be as large as possible. We recall the known primary construction of such codes with cyclic codes, and investigate other constructions, with expanded Reed-Solomon codes and ...

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...
