چکیده

In this paper we investigate relations between several masking schemes. We show that the Ishai–Sahai–Wagner private circuits construction is closely related to Threshold Implementations and the Trichina gate. The implications of this observation are manifold. We point out a higher-order weakness in higher-order Threshold Implementations, suggest a mitigation and provide new sharings that use a lower number of input shares.

Consolidating Inner Product Masking

Masking schemes are a prominent countermeasure to defeat power analysis attacks. One of their core ingredients is the encoding function. Due to its simplicity and comparably low complexity overheads, many masking schemes are based on a Boolean encoding. Yet, several recent works have proposed masking schemes that are based on alternative encoding functions. One such example is the inner product...

Parallel Implementations of Masking Schemes and the Bounded Moment Leakage Model

In this paper, we provide a necessary clarification of the good security properties that can be obtained from parallel implementations of masking schemes. For this purpose, we first argue that (i) the probing model is not straightforward to interpret, since it more naturally captures the intuitions of serial implementations, and (ii) the noisy leakage model is not always convenient, e.g. when c...

CPA on COLM Authenticated Cipher and the Protection Using Domain-Oriented Masking

Authenticated encryption schemes are important cryptographic primitives that received extensive attention recently. They can provide both confidentiality and authenticity services, simultaneously. Correlation power analysis (CPA) can be a thread for authenticated ciphers, similar to the any physical implementation of any other cryptographic scheme. In this paper, a three-step CPA attack against...

Reconciling d+1 Masking in Hardware and Software

The continually growing number of security-related autonomous devices requires efficient mechanisms to counteract low-cost side-channel analysis (SCA) attacks. Masking provides high resistance against SCA at an adjustable level of security. A high level of SCA resistance, however, goes hand in hand with an increasing demand for fresh randomness which drastically increases the implementation cos...

Analysis and Design of Masking Schemes for Secure Cryptographic Implementations ; Analyse en ontwerp van maskeringsschema's voor veilige cryptografische implementaties

Masking is the central topic of this thesis based on publications. Masking is a technique that allows the secure execution of cryptographic algorithms in untrusted environments. More concretely, masking provides security guarantees even if an adversary observes side-channel leakage. We first propose a methodology to attack masked implementations more quickly. Our method is relevant in practice ...
