CRYPTOGRAPHIC DEVICES AND METHODS FOR GENERATING AND VERIFYING LINEARLY HOMOMORPHIC STRUCTURE-PRESERVING SIGNATURES

摘要

The present invention relates to cryptographic devices and methods for generating and verifying linearly homomorphic structure-preserving signatures. In a processor of a device, signature elements are calculated by using a signature key and the signature including the signature elements are outputted. Also, a fully-fledged scheme and a context-hiding scheme are provided.;COPYRIGHT KIPO 2014
