Lesamnta-LW Revisited: Improved Security Analysis of Primitive and New PRF Mode we propose a new mode for building a pseudo-random function (PRF) based on Lesamnta-LW. The previous PRF modes can only process 128 bits per block-cipher call, while the new mode can process 256 bits to achieve the double throughput. We prove its security both in the standard model and the ideal cipher model.

Trapdoor Delegation and HIBE from Middle-Product LWE in Standard Modeler by proposing a novel trapdoor delegation mechanism for an extended family of polynomials from which we construct, for the first time, a Hierachical IBE scheme from MPLWE. Our Hierarchy IBE scheme is provably secure in the standard model.

Efficient AGCD-Based Homomorphic Encryption for Matrix and Vector Arithmetichomomorphic products between 128-dimensional vectors and . matrices in less than one second. We show how to use our scheme to homomorphically evaluate nondeterministic finite automata and also a Naïve Bayes Classifier.

Improving the Efficiency of Re-randomizable and Replayable CCA Secure Public Key Encryption scheme is more efficient than the state-of-art Rand-RCCA PKE scheme of Faonio et al. (ASIACRYPT’19) but it achieves a weaker re-randomization property. On the other hand, our scheme achieves a strictly stronger re-randomization property than the PKE scheme of Phan and Pointcheval (ASIACRYPT’04).

SomePSS protocols can handle batching of . secrets, but all of them are for the honest majority setting. The techniques typically used to accomplish such batching decrease the
