New approach to practical leakage-resilient public-key cryptography [PDF]
Journal of Mathematical Cryptology, 2020 We present a new approach to construct several leakage-resilient cryptographic primitives, including leakage-resilient public-key encryption (PKE) schemes, authenticated key exchange (AKE) protocols and low-latency key exchange (LLKE) protocols.

Leakage-Resilient Cryptography [PDF]
2008 49th Annual IEEE Symposium on Foundations of Computer Science, 2008 We construct a stream-cipher S whose implementation is secure even if a bounded amount of arbitrary (adversarially chosen) information on the internal state ofS is leaked during computation. This captures all possible side-channel attacks on S where the amount of information leaked in a given period is bounded, but overall can be arbitrary large.

IEEE Access, 2020 Certificateless public-key cryptography has conquered both the certificate management problem in the traditional public-key cryptography and the key escrow problem in the ID-based public-key cryptography. Certificateless authenticated key exchange (CLAKE)

Leakage Resilient Cryptography in Practice [PDF]
Information Security and Cryptography, 2010 Theoretical treatments of physical attacks have recently attracted the attention of the cryptographic community, as witnessed by various publications, e.g., [1, 17, 22, 24, 29, 31, 33, 34, 42]. These works consider adversaries enhanced with abilities such as inserting faults during a computation or monitoring side-channel leakages.

New Developments in Leakage-Resilient Cryptography [PDF]
Lecture Notes in Computer Science, 2011 Much of modern cryptography is predicated on the assumption that users have secrets which are generated using perfect randomness, and kept perfectly secret from an attacker. The attacker is then constrained to black-box (input/output) access to the user's program.

Leakage-Resilient Certificate-Based Signature Resistant to Side-Channel Attacks
IEEE Access, 2019 Certificate-based cryptography is an attractive public-key setting, and it not only simplifies certificate management in the traditional public-key cryptography but also eliminates the key escrow problem inherent in the identity-based cryptography ...

On the leakage-resilient key exchange
Journal of Mathematical Cryptology, 2017 Typically, secure channels are constructed from an authenticated key exchange (AKE) protocol, which authenticates the communicating parties based on long-term public keys and establishes secret session keys.

High speed ASIC implementations of leakage-resilient cryptography
2018 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2018 Embedded devices in the Internet-of-Things require encryption functionalities to secure their communication. However, side-channel attacks and in particular differential power analysis (DPA) attacks pose a serious threat to cryptographic implementations.

Exploring Integrity of AEADs with Faults: Definitions and Constructions
IACR Transactions on Symmetric Cryptology, 2022 Implementation-based attacks are major concerns for modern cryptography. For symmetric-key cryptography, a significant amount of exploration has taken place in this regard for primitives such as block ciphers.

On Provable White-Box Security in the Strong Incompressibility Model
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Incompressibility is a popular security notion for white-box cryptography and captures that a large encryption program cannot be compressed without losing functionality. Fouque, Karpman, Kirchner and Minaud (FKKM) defined strong incompressibility, where
