Defending cache memory against cold-boot attacks boosted by power or EM radiation analysis [PDF]
, 2017 Some algorithms running with compromised data select cache memory as a type of secure memory where data is confined and not transferred to main memory. However, cold-boot attacks that target cache memories exploit the data remanence. Thus, a sudden power

Linear Repairing Codes and Side-Channel Attacks
Transactions on Cryptographic Hardware and Embedded Systems, 2018 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 d-degree polynomial into n ≥ d + 1 public points to ...

Strengthening Sequential Side-Channel Attacks Through Change Detection
Transactions on Cryptographic Hardware and Embedded Systems, 2020 The sequential structure of some side-channel attacks makes them subject to error propagation, i.e. when an error occurs during the recovery of some part of a secret key, all the following guesses might as well be chosen randomly.

An Evaluation of Power Side-Channel Resistance for RNS Secure Logic
Sensors, 2022 In this paper, residue number system (RNS) based logic is proposed as a protection against power side-channel attacks. Every input to RNS logic is encrypted as a share of the original input in the residue domain through modulus values.

Insecurity of detector-device-independent quantum key distribution [PDF]
, 2016 Detector-device-independent quantum key distribution (ddiQKD) held the promise of being robust to detector side-channels, a major security loophole in QKD implementations. In contrast to what has been claimed, however, we demonstrate that the security of

Will You Cross the Threshold for Me?
Transactions on Cryptographic Hardware and Embedded Systems, 2021 In this work, we propose generic and novel side-channel assisted chosenciphertext attacks on NTRU-based key encapsulation mechanisms (KEMs). These KEMs are IND-CCA secure, that is, they are secure in the chosen-ciphertext model.

Kangaroos in Side-Channel Attacks [PDF]
, 2015 Side-channel attacks are a powerful tool to discover the cryptographic secrets of a chip or other device but only too often do they require too many traces or leave too many possible keys to explore. In this paper we show that for side channel attacks on discrete-logarithm-based systems significantly more unknown bits can be handled by using Pollard's ...

Attacks on IoT: Side-Channel Power Acquisition Framework for Intrusion Detection
Future Internet, 2023 This study proposes the wider use of non-intrusive side-channel power data in cybersecurity for intrusion detection. An in-depth analysis of side-channel IoT power behaviour is performed on two well-known IoT devices—a Raspberry Pi 3 model B and a ...

Experimental measurement-device-independent quantum digital signatures over a metropolitan network [PDF]
, 2017 Quantum digital signatures (QDS) provide a means for signing electronic communications with informationtheoretic security. However, all previous demonstrations of quantum digital signatures assume trusted measurement devices. This renders them vulnerable

Side channel attacks for architecture extraction of neural networks
CAAI Transactions on Intelligence Technology, 2021 Side channel attacks (SCAs) on neural networks (NNs) are particularly efficient for retrieving secret information from NNs. We differentiate multiple types of threat scenarios regarding what kind of information is available before the attack and its ...
