Lattice trapdoors are an important primitive used in a wide range of cryptographic protocols, such as identity-based encryption (IBE), attribute-based encryption, functional and program obfuscation. In this paper, we present software implementations the Gentry-Peikert-Vaikuntanathan (GPV) digital signature, IBE ciphertext-policy (CP-ABE) schemes based on efficient Gaussian sampling algorithm for trapdoor lattices, demonstrate that these three protocols practical. One aspect our...
We report on our implementation of a new Gaussian sampling algorithm for lattice trapdoors. Lattice trapdoors are used in wide array lattice-based cryptographic schemes including digital signatures, attributed-based encryption, program obfuscation and others. Our provides trapdoor lattices with prime moduli, supports both single- multi-threaded execution. experimentally evaluate through its use the GPV hash-and-sign signature scheme as benchmark. compare design prior work reported...
We address the practicality challenges of secure program obfuscation by implementing, optimizing, and experimentally assessing an approach to securely obfuscate conjunction programs proposed in [1].
