ePrint Report: A Lattice-based Publish-Subscribe Communication Protocol using Accelerated Homomorphic Encryption Primitives

Anes Abdennebi, Erkay Savaş

Key-policy attribute-based encryption scheme (KP-ABE) uses a set of attributes as public keys for encryption. It allows homomorphic evaluation of ciphertext into another ciphertext of the same message, which can be decrypted if a certain access policy based on the attributes is satisfied. A lattice-based KP-ABE scheme is reported in several works in the literature, and its software implementation is available in an open-source …
