Leakage-Resilient Certificateless Signcryption Scheme Under a Continual Leakage Model
Signature can be used to verify the integrity of both a message and the identity of a signer, whereas encryption can be used to ensure the confidentiality of a message.

Leakage-Resilient Certificate-based Key Encapsulation Scheme Resistant to Continual Leakage
In the past, the security of most public-key encryption or key encapsulation schemes is shown in an ideal model, where private keys, secret keys and random values are assumed to be absolutely secure to adversaries.

Leakage-Resilient Anonymous Multi-Receiver Certificate-Based Key Encapsulation Scheme
Key encapsulation schemes in public key system (PKS) can be used to protect sensitive or private data. Unlike traditional PKS and identity-based PKS, certificate-based PKS (CB-PKS) not only avoids the establishment of complex public key infrastructures ...

Fallen Sanctuary: A Higher-Order and Leakage-Resilient Rekeying Scheme
This paper presents a provably secure, higher-order, and leakage-resilient (LR) rekeying scheme named LR Rekeying with Random oracle Repetition (LR4), along with a quantitative security evaluation methodology.

Hybrid Code Lifting on Space-Hard Block Ciphers
There is a high demand for whitebox cryptography from the practical use of encryption in untrusted environments. It has been actively discussed for two decades since Chow et al. presented the whitebox implementation of DES and AES. The goal is to resist

Leakage-Resilient Certificate-Based Authenticated Key Exchange Protocol
Certificate-based public key cryptography (CB-PKC) removes the problem of certificate management in traditional public key systems and avoids the key escrow problem in identity-based public key systems.

Multi-location Leakage Resilient Cryptography [PDF]
Understanding and modeling leakage in the context of cryptographic systems (connecting physical protection of keys and cryptographic operation) is an emerging area with many missing issues and hard to understand aspects. In this work we initiate the study of leakage out of cryptographic devices when the operation is inherently replicated in multiple ...

Improved Leakage-Resistant Authenticated Encryption based on Hardware AES Coprocessors
We revisit Unterstein et al.’s leakage-resilient authenticated encryption scheme from CHES 2020. Its main goal is to enable secure software updates by leveraging unprotected (e.g., AES, SHA256) coprocessors available on low-end microcontrollers.
