Proxy Re-Encryption and Re-Signatures from Lattices

WebbProxy Re-encryption from Lattices. We propose a new unidirectional proxy re-encryption scheme based on the hardness of the LWE problem. Our construction is collusionsafe and does not require any trusted authority for the re-encryption key generation. We extend a recent trapdoor definition.
