Cross-primitive comparison in CP-ABE

Journal of Mathematical Cryptology
Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is a cornerstone technique for fine-grained access control in encrypted data sharing, with pairing-based schemes having established the de facto standard.

Smaller public keys for MinRank-based schemes

Journal of Mathematical Cryptology
MinRank is an NP-complete problem in linear algebra whose characteristics make it attractive to build post-quantum cryptographic primitives. Several MinRank-based digital signature schemes have been proposed.

Approaches to MEV in DAG-based DLTs

Journal of Mathematical Cryptology
Maximal extractable value (MEV) refers to value extracted from a decentralised ledger by manipulation of transaction ordering. Although MEV can be challenging to define consistently across contexts, it is widely recognised as a significant threat to the ...

Efficiency of SIDH-based signatures (yes, SIDH)

Journal of Mathematical Cryptology
In this note, we assess the efficiency of a supersingular isogeny Diffie-Hellman (SIDH)-based digital signature built on a weaker variant of a recent identification protocol proposed by Basso et al.

Threshold RSA Based on the General Chinese Remainder Theorem

, 2008
. In this paper we combine the threshold secret sharing schemes based on the general Chinese remainder theorem with the RSA cryptosystem in order to get threshold decryption or signature generation, as an alternative to the classical solutions based on ...

SUM GRAPH BASED ACCESS STRUCTURE IN A SECRET SHARING SCHEME

, 2008
. Secret sharing scheme is a method to distribute secret information to a set P of participants so that only authorised subsets of P can reconstruct the secret.
