Journal ArticleDOI
Identity-Based Remote Data Integrity Checking With Perfect Data Privacy Preserving for Cloud Storage
TL;DR: This paper proposes a new construction of identity-based (ID-based) RDIC protocol by making use of key-homomorphic cryptographic primitive to reduce the system complexity and the cost for establishing and managing the public key authentication framework in PKI-based RDIC schemes.
Proceedings ArticleDOI
Attribute-based signature and its applications
TL;DR: Two efficient ABS constructions supporting flexible threshold predicate are proposed by exploring a new technique for signature signing and are provably secure in the random oracle model, while the second construction does not rely on therandom oracle assumption.
Proceedings ArticleDOI
Malicious KGC attacks in certificateless cryptography
TL;DR: Wang et al. as discussed by the authors proposed new security models that remove this assumption for both certificateless signature and encryption schemes and showed that a class of certificateless encryption and signature schemes proposed previously are insecure.
Proceedings ArticleDOI
Self-Generated-Certificate Public Key Cryptography and certificateless signature/encryption scheme in the standard model: extended abstract
TL;DR: A certificateless signature and a certificateless encryption scheme with concrete implementation that are all provably secure in the standard model, which are the first in the literature regardless of the generic constructions by Yum and Lee which may contain security weaknesses as pointed out by others.
Book ChapterDOI
RingCT 2.0: A Compact Accumulator-Based (Linkable Ring Signature) Protocol for Blockchain Cryptocurrency Monero
TL;DR: In this article, the authors study the necessary properties and security requirements of Ring Confidential Transaction (RingCT) protocol deployed in the popular anonymous cryptocurrency Monero and present several formal security definitions according to its application in Monero.
