In this paper we introduce the first group key transfer protocolsecure in the lattice-based environment which achieves anonymity of the membersagainst each others. This issue is almost absent in the key transfer protocolsfrom the literature but we argue it is a practical property. We use two essentialcryptographic primitives for our protocol: lattice Diffie-Hellman key exchangederived from Regev’s work [11] and a public key cryptosystem secure from theLWE hardness and we achieve IND-CPA anonymity.
