Simulation-Based Secure Functional Encryption in the Random Oracle Model [PDF]
, 2015 One of the main lines of research in functional encryption FE has consisted in studying the security notions for FE and their achievability. This study was initiated by [Boneh et al. --- TCC'11, O'Neilli¾?--- ePrint'10] where it was first shown that for FE the indistinguishability-based IND security notion is not sufficient in the sense that there are ...

Bayesian definition of random sequences with respect to conditional probabilities
, 2022 We study Martin-L\"{o}f random (ML-random) points on computable probability measures on sample and parameter spaces (Bayes models). We consider four variants of conditional random sequences with respect to the conditional distributions: two of them are ...

Secure identity-based encryption in the quantum random oracle model [PDF]
International Journal of Quantum Information, 2012 We give the first proof of security for an identity-based encryption (IBE) scheme in the quantum random oracle model. This is the first proof of security for any scheme in this model that does not rely on the assumed existence of so-called quantum-secure pseudorandom functions (PRFs). Our techniques are quite general and we use them to obtain security

Cryptanalysis and improvement of an efficient certificateless signature scheme
, 2008 In traditional digital signature schemes, certificates signed by a trusted party are required to ensure the authenticity of the public key. In Asiacrypt 2003, the concept of certificateless signature scheme was introduced.

An Identity-Based Group Signature with Membership Revocation in the Standard Model [PDF]
, 2010 Group signatures allow group members to sign an arbitrary number\ud of messages on behalf of the group without revealing their\ud identity. Under certain circumstances the group manager holding a\ud tracing key can reveal the identity of the signer from ...

On the security of the Courtois-Finiasz-Sendrier signature
Open Mathematics, 2018 We prove that a variant of the Courtois-Finiasz-Sendrier signature is strongly existentially unforgeable under chosen message attack in the random oracle model, assuming hardness of the Permuted Goppa Syndrome Decoding Problem (also known as the ...
