With the explosive data growth arise from internet of things, how to ensure information security is facing unprecedented challenges. In this paper, a joint PHY/MAC layer security scheme with artificial noise design in singular value decomposition (SVD) based multiple input multiple output hybrid automatic retransmission request (MIMO HARQ) system is proposed to resolve the problem of low data rates in existing cross-layer security design and further adapt to the high data rate requirement of 5G. First, the SVD was applied to simplify MIMO systems into several parallel sub-channels employing HARQ protocol. Then, different from traditional null space based artificial noise design, the artificial noise design, which is dependent on the characteristics of channel states and transmission rounds, is detailed presented. Finally, the analytical and simulation results proved that with the help of the proposed artificial noise, both the information security and data rate performance can be significantly improved compared with that in single input single output (SISO) system.

Proofs of Data Possession/Retrievability (PoDP/PoR) schemes are essential to cloud storage services, since they can increase clients' confidence on the integrity and availability of their data. The majority of PoDP/PoR schemes are constructed from homomorphic linear authentication (HLA) schemes, which decrease the price of communication between the client and the server. In this paper, a new subclass of authentication codes, named ε-authentication codes, is proposed, and a modular construction of HLA schemes from ε-authentication codes is presented. We prove that the security notions of HLA schemes are closely related to the size of the authenticator/tag space and the successful probability of impersonation attacks (with non-zero source states) of the underlying ε-authentication codes. We show that most of HLA schemes used for the PoDP/PoR schemes are instantiations of our modular construction from some ε-authentication codes. Following this line, an algebraic-curves-based ε-authentication code yields a new HLA scheme.
