“…This efficiency quantifies the expected back-off in terms of data rates when part of the resources (power and frequency) are used to enable the generation of secret keys at the physical layer. In future work, we will compare the efficiency achieved to that of actual approaches currently used in 5G by accounting for the actual delays incurred due to the PKE key agreement operations [20].…”

“…With respect to authentication, physical unclonable functions (PUFs), firstly introduced in [17] (based on the idea of physical one-way functions [18]), [19] could also enhance authentication and key agreement in demanding scenarios, including (but not limited to) device to device and tactile Internet. We note that others also point to using physical layer security to reduce the resource overhead in URLLC [20].…”

With the emergence of 5G low-latency applications, such as haptics and V2X, low-complexity and low-latency security mechanisms are needed. Promising lightweight mechanisms include physical unclonable functions (PUF) and secret key generation (SKG) at the physical layer, as considered in this paper. In this framework, we propose (i) a zero round trip time (0-RTT) resumption authentication protocol combining PUF and SKG processes, (ii) a novel authenticated encryption (AE) using SKG, and (iii) pipelining of the AE SKG and the encrypted data transfer in order to reduce latency. Implementing the pipelining at PHY, we investigate a parallel SKG approach for multi-carrier systems, where a subset of the subcarriers are used for SKG and the rest for data transmission. The optimal solution to this PHY resource allocation problem is identified under security, power, and delay constraints, by formulating the subcarrier scheduling as a subset-sum 0 − 1 knapsack optimization. A heuristic algorithm of linear complexity is proposed and shown to incur negligible loss with respect to the optimal dynamic programming solution. All of the proposed mechanisms have the potential to pave the way for a new breed of latency aware security protocols.

“…For example, in ultra reliable low latency communication systems (URLLC) it is noted that "for a URLLC service with higher speed than 65kbps, the 3GGP Release 15 radio access network (RAN) cannot fulfill the quality of service (QoS) requirement while enforcing user plane integrity protection" [3]. Others also point to using physical layer security to reduce the resource overhead in URLLC [4].…”

In computational complexity and latency constrained emerging 5G applications, e.g., autonomous vehicles, haptic communications and enhanced reality, secret key generation (SKG) at the physical layer could be considered as an alternative to currently used key agreement schemes. In this framework, we study the optimal subcarrier scheduling in multicarrier systems when a subset of the subcarriers are used for SKG and the rest for data transmission, under both security and power constraints. The amount of data that can be transmitted with a single key is determined by the cryptographic suites used, so that realistic key rate constraints can be identified. This allows us to formulate the subcarrier allocation as a subset-sum 0 − 1 knapsack optimization problem that we solve using i) the standard dynamic programming approach and ii) a greedy heuristic approach of linear complexity. We show that the proposed heuristic induces virtually no loss in performance. Furthermore, a comparison with a baseline scheme in which SKG and data transfer are performed sequentially, shows that the proposed parallel approach offers gains in terms of efficiency.
