Abstract
Authentication has been adopted in many areas, but most of these authentication schemes are built using traditional cryptographic primitives. It is widely believed that such primitives are not resistant to quantum algorithms. To deal with those quantum attacks, lattice-based cryptography was introduced by Ajtai in 1996. To the best of our knowledge, the existing lattice-based authentication schemes are based on a lattice-based public key encryption called NTRU: a ring-based public key cryptosystem, proposed by Hoffstein, Pipher, and Silverman in 1998. However, these schemes only support the case of a single user. In view of the aforementioned issue, we propose the first lattice-based group authentication scheme. The proposed scheme is secure against replay attacks and man-in-the-middle attacks. Moreover, compared with the existing lattice-based authentication schemes, ours provides the most efficient method to agree upon a session key among a group of users after mutual authentication.
Highlights
Nowadays, authentication has been adopted in many areas, such as radio frequency identification (RFID), cloud computing, wireless sensor networks, internet of things (IoT), etc.Authentication schemes can be separated into two types: one is individual-oriented authentication, and another is group-oriented authentication
To the best of our knowledge, the existing lattice-based authentication schemes [3,4] are based on a lattice-based public key encryption called NTRU encryption [5], proposed by Hoffstein, Pipher, and Silverman in 1998
Most authentication schemes are built on traditional cryptographic primitives
Summary
Authentication has been adopted in many areas, such as radio frequency identification (RFID), cloud computing, wireless sensor networks, internet of things (IoT), etc. Such a cryptographic primitive can be applied heavily to many-to-many network environments, e.g., Internet of Things or RFID Most of these authentication schemes are built on traditional cryptographic primitives, e.g., RSA and ElGamal, where the cryptosystems are constructed based on discrete logarithm or factorization. To the best of our knowledge, the existing lattice-based authentication schemes [3,4] are based on a lattice-based public key encryption called NTRU encryption [5], proposed by Hoffstein, Pipher, and Silverman in 1998. These two schemes support only the case of a single user. Compared with the existing lattice-based authentication schemes, our scheme provides the most efficient authentication protocol in terms of the total cost to generate a session key among a group of users after mutual authentication
