A relation calculus for reasoning about t-probing security [PDF]
Journal of Cryptographic Engineering, 2022 AbstractIn the context of side-channel attacks against cryptographic circuits, t-probing security characterizes the amount of information derivable about sensitive values (e.g., keys) by observing t output/internal values. Non-interference is a useful mathematical tool used by researchers to assess the probing security of a circuit which employs ...

Random Probing Security: Verification, Composition, Expansion and New Constructions [PDF]
IACR Cryptology ePrint Archive, 2020 The masking countermeasure is among the most powerful countermeasures to counteract side-channel attacks. Leakage models have been exhibited to theoretically reason on the security of such masked implementations. So far, the most widely used leakage model is the probing model defined by Ishai, Sahai, and Wagner at (CRYPTO 2003).

An Algebraic Approach for Evaluating Random Probing Security With Application to AES
Transactions on Cryptographic Hardware and Embedded SystemsWe employ an algebraic approach to estimate the success rate of a sidechannel adversary attacking secrets of a masked circuit within the Random Probing Model (RPM), where intermediate variables of the implementation leak with a probability p. Our method

garak: A Framework for Security Probing Large Language Models [PDF]
arXiv.orgAs Large Language Models (LLMs) are deployed and integrated into thousands of applications, the need for scalable evaluation of how models respond to adversarial attacks grows rapidly. However, LLM security is a moving target: models produce unpredictable output, are constantly updated, and the potential adversary is highly diverse: anyone with access ...

Transactions on Cryptographic Hardware and Embedded Systems, 2021 There exists many masking schemes to protect implementations of cryptographic operations against side-channel attacks. It is common practice to analyze the security of these schemes in the probing model, or its variant which takes into account physical ...

Composable Gadgets with Reused Fresh Masks
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Albeit its many benefits, masking cryptographic hardware designs has proven to be a non-trivial and error-prone task, even for experienced engineers.

Tunnel enabled programmable switches obfuscate network topology to defend against link flooding reconnaissance in software defined networking [PDF]
Scientific ReportsRecently, Software-Defined Networking (SDN) has emerged as an increasingly popular network paradigm due to its virtualization capabilities and flexibility. However, its robustness in link connectivity is threatened by Link Flooding Attacks (LFAs).
