Certificate-Based Encryption Resilient to Key Leakage
Certificate-based encryption (CBE) is an important class of public key encryption but the existing schemes are secure only under the premise that the decryption key (or private key) and master private key are absolutely secret. In fact, a lot of side channel attacks and cold boot attacks can leak secret information of a cryptographic system. In this case, the security of the cryptographic syste...
متن کاملCryptography Resilient to Continual Memory Leakage
In recent years, there has been a major effort to design cryptographic schemes that remain secure even if part of the secret key is leaked. This is due to a recent proliferation of side channel attacks which, through various physical means, can recover part of the secret key. We explore the possibility of achieving security even with continual leakage, i.e., even if some information is leaked e...
متن کاملIdentity-Based Encryption Resilient to Continual Auxiliary Leakage
We devise the first identity-based encryption (IBE) that remains secure even when the adversary is equipped with auxiliary input (STOC ’09) – any computationally uninvertible function of the master secret key and the identity-based secret key. In particular, this is more general than the tolerance of Chow et al.’s IBE schemes (CCS ’10) and Lewko et al.’s IBE schemes (TCC ’11), in which the leak...
متن کاملPublic-Key Cryptosystems Resilient to Key Leakage
Most of the work in the analysis of cryptographic schemes is concentrated in abstract adversarial models that do not capture sidechannel attacks. Such attacks exploit various forms of unintended information leakage, which is inherent to almost all physical implementations. Inspired by recent side-channel attacks, especially the “cold boot attacks”, Akavia, Goldwasser and Vaikuntanathan (TCC ’09...
متن کاملWeak-Key Leakage Resilient Cryptography
In traditional cryptography, the standard way of examining the security of a scheme is to analyze it in a black-box manner, capturing no side channel attacks which exploit various forms of unintended information leakages and do threaten the practical security of the scheme. One way to protect against such attacks aforementioned is to extend the traditional models so as to capture them. Early mo...
