A novel class of covert channel, out-of-band covert channels, is presented by extending
Simmons' prisoners' problem. This new class of covert channel is established by surveying …

Embedded software is developed under the assumption that hardware execution is always
correct. Fault attacks break and exploit that assumption. Through the careful introduction of …

Secure circuits are prone to a wide range of physical attacks. Among those are fault attacks
based on modifying the circuit environment in order to change its behaviour or to induce …

True random number generators (TRNGs) are the basic building blocks of cryptographic
implementations. They are used to generate random numbers required for security …

Secure circuits are prone to a wide range of physical attacks. Among them, fault attacks are
based on modifying the circuit environment in order to change its behaviour or to induce …

Abstract At Indocrypt 2021, Hermelink, Pessl, and Pöppelmann presented a fault attack
against Kyber in which a system of linear inequalities over the private key is generated and …

Fault injection attacks have proven to be a powerful tool to exploit the implementation
weaknesses of cryptographic algorithms. Several techniques perturbing the computation of …

Side-channel attacks and fault attacks use the physical interactions with cryptographic
devices to achieve the shortcuts of recovering the secret key. For side-channel attacks …

When complex functions, for example, substitution boxes of block ciphers, are realized in
hardware, timing attributes of the underlying combinational circuit depend on the …

Traditional detection countermeasures against fault attacks have been criticized as insecure
because of the fragile comparison operation that can be maliciously bypassed. In order to …
