Complementary Dual Codes for Counter-measures to Side-Channel Attacks
"... Abstract. 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 investigate primary constructions of s ..."

Side-channel attacks based on linear approximations
"... Abstract. 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 d ..."

T.: Towards Side-Channel Resistant Implementations of QC-MDPC McEliece Encryption on Constrained Devices
- Post-Quantum Cryptography, Lecture Notes in Computer Science
, 2014
"... Abstract. Recent advances in code-based cryptography paved new ways for efficient asymmetric cryptosystems that combine decent performance with moderate key sizes. In this context, Misoczki et al. recently proposed the use of quasi-cyclic MDPC (QC-MDPC) codes for the McEliece cryp-tosystem. It was s ..."

Formal Study of a Countermeasure Against Side-Channel Attacks Location. SEN group of the COMELEC department at Telecom ParisTech (37 rue Dareau, 75014,
"... Context. In applications such as cryptography or real-time systems, formal methods are used to prove functional properties on the critical parts of the code. Specifically in cryptography, some non-functional properties are also important, but are not typically certified by formal proofs yet. One exa ..."

to extract sensitive information (e.g., secret keys) [3, 2, 4]. Many existing countermeasures against side-channel attacks are implemented at the hardware level, especially for smartcards. However, software level countermeasures are also very important, not only in embedded systems where the hardware cannot
Masked Dual-Rail Pre-charge Logic: DPA-Resistance Without Routing Constraints
- Systems – CHES 2005, 7th International Workshop
, 2005
"... Abstract. During the last years, several logic styles that counteract side-channel attacks have been proposed. They all have in common that their level of resistance heavily depends on implementation constraints that are costly to satisfy. For example, the capacitive load of complementary wires in a ..."

The Program Counter Security Model: Automatic Detection and Removal of Control-Flow Side Channel Attacks
- In Cryptology ePrint Archive, Report 2005/368
, 2005
"... Abstract. We introduce new methods for detecting control-flow side channel attacks, transforming C source code to eliminate such attacks, and checking that the transformed code is free of control-flow side channels. We model control-flow side channels with a program counter transcript, in which the ..."

MUTE-AES: A Multiprocessor Architecture to prevent Power Analysis based Side Channel Attack of the AES Algorithm
"... Abstract — Side channel attack based upon the analysis of power traces is an effective way of obtaining the encryption key from secure processors. Power traces can be used to detect bitflips which betray the secure key. Balancing the bitflips with opposite bitflips have been proposed, by the use of ..."

Higher-order CIS codes
, 2014
"... We introduce complementary information set codes of higher-order. A binary linear code of length tk and dimension k is called a complementary information set code of order t (t-CIS code for short) if it has t pairwise disjoint information sets. The duals of such codes permit to reduce the cost of ma ..."

As in the case of codes for error correction, given the length and the dimension of a t-CIS code, we look for the highest possible minimum distance. In this paper, this new class of codes is investigated. The existence of good long CIS codes

In contrast to classical cryptanalysis, in which the mathematical properties of a cipher are exploited, side-channel analysis tries to reveal a cryptographic key by evaluating leakage information that emanates from a physi ..."
