Efficient forward secure identity-based shorter signature from lattice

Abstract

All regular cryptographic schemes rely on the security of the secret key. However, with the explosive use of some relatively insecure mobile devices, the key exposure problem has become more aggravated. In this paper, we propose an efficient forward secure identitybased signature (FSIBS) scheme from lattice assumption, with its security based on the small… (More)
