Cryptanalysis of Compact Certificateless Aggregate Signature Schemes for HWMSNs and VANETs
IEEE AccessCertificateless cryptosystems resolve the critical problems in public-key cryptosystems and identity-based cryptosystems. A certificateless aggregate signature scheme aggregates multiple signatures of multiple signers into a single signature that ...

IET Communications, Volume 18, Issue 4, Page 309-321, March 2024.(1) A blockchain‐based efficient data‐sharing scheme is proposed, which employs the ciphertext policy attribute‐based encryption algorithm to enable fine‐grained sharing of data resources. (2) An anonymous identity authentication method based on ring signatures is proposed, which can effectively protect the user's identity privacy and transaction ...

Certificateless Signature Scheme Based on Rabin Algorithm and Discrete Logarithm [PDF]
, 2016 Certificateless signature can effectively immue the key escrow problem in the identity-based signature scheme. But the security of the most certificateless signatures usually depends on only one mathematical hard problem, which makes the signature ...

IET Information Security, Volume 2024, Issue 1, 2024.Named Data Networking (NDN) is a promising network architecture that differs from the traditional TCP/IP network, as it focuses on data rather than the host. A new secure model is required to provide the data‐oriented trust instead of the host‐oriented trust.
