An algebraic framework for Diffie-Hellman assumptions
(2017-01)
Article
Open AccessWe put forward a new algebraic framework to generalize and analyze Di e-Hellman like Decisional Assumptions which allows us to argue about security and applications by considering only algebraic properties. Our D`;k-MDDH ... -

Constant size ciphertexts in threshold attribute-based encryption
(Springer Verlag, 2010)
Conference report
Open AccessAttribute-based cryptography has emerged in the last years as a promising primitive for digital security. For instance, it provides good solutions to the problem of anonymous access control. In a ciphertextpolicy attribute-based ... -
Matrix computational assumptions in multilinear groups
(2015-04-20)
Research report
Open AccessWe put forward a new family of computational assumptions, the Kernel Matrix Di e- Hellman Assumption. Given some matrix A sampled from some distribution D `;k , the kernel as- sumption says that it is hard to nd \in the exponent -
