“…There are a few recent research on secrecy oriented user association schemes in HCNs. Wang et al showed that a simple truncated user association scheme that assigns users to BSs whose transmitted signal strength must be above a given threshold can improve system secrecy throughput and secrecy probability [11]. Zhou et al showed that a non-best user association scheme that assigns a typical user to a non-best BS in terms of average received signal power can significantly improve secrecy probability [12].…”

“…The aforementioned assumptions would require that this eavesdropper intercept and decrypt entire network traffic, regardless of its spatial location and physical characteristics. While it is reasonable to consider this as a worse-case scenario [9,11,17,34,35], in practical situations the eavesdropping capabilities of adversaries are limited and it is not possible for them to eavesdrop on all users. Then eavesdroppers have to make strategic decisions on which users they would like to eavesdrop on.…”

“…Naturally, one may wonder whether user association schemes can also be specifically designed to boost secrecy performance. A few recent works [11–13] confirm that user association is also a valuable tool we can leverage to further improve system secrecy performance. That motivate us to investigate a user association scheme that aims to improve secrecy performance under the threat of strategic and colluding adversaries.…”

Network densification is recognized as the key technology to meet the ever growing demand of data traffic in next generation wireless networks. However the proliferation of small cell base stations (SCBSs) introduces vulnerabilities to information security, as they are prone to eavesdropping attacks. In this paper, it is studied how user association strategies can be specifically tailored to meet this security challenge in a ultra dense heterogeneous cellular network(UDHCN) with a group of colluding eavesdroppers. In particular, the situation is considered where eavesdroppers may have limited capabilities in intercepting and decoding data traffic. In this setting each eavesdropper has to make its own decision on eavesdropping targets, and they are able to take concerted actions to sabotage information security. To address this challenge, a zero sum game framework to reflect the conflicting interests of users and eavesdroppers is proposed and a user association scheme is devised that aims to maximize system sum secrecy rate against these adversaries whose actions intend to minimize sum secrecy rate. The case that all adversaries have limited eavesdropping capabilities is first considered, and it is shown that the corresponding zero sum game is indeed a bilinear game, and its Nash equilibrium solution can be readily approximated using a saddle point Frank Wolfe(SP-FW)algorithm. Then the framework is extended to the case where adversaries with a diverse configuration of eavesdropping capabilities exist. In this case, it is shown that the underlying minimax optimization problem is indeed a nonsmooth convex-nonconcave one. A two stage method is proposed by first smoothing the objective function with a Hermite cubic polynomial approximation, and then obtaining a nearly stationary solution via a recently proposed proximal point gradient descent method. Simulation results show that the proposed framework leads to significant increases in sum secrecy rate and secrecy probability against both the capability-limited adversaries and a hybrid type of adversaries.

“…In [ 27 ], the UE selects the BS that provides the highest secrecy rate, but inter-cell interference is not considered, while it is a basic element of UDNs. Differently in [ 28 ], in-band interference is considered and the maximum secrecy rate association is approximated using the Maclaurin formulation. In [ 29 ], the maximum secure area is considered.…”

The last decades have been characterized by an exponential increase in digital services. The demand is foreseen to further increase in the next years, and mobile networks will have to mandatorily supply connections to enable digital services with very different requirements, from ultra high speed to ultra low latency. The deployment and the coexistence of cells of different size, from femto to macro, will be one of the key elements for providing such pervasive wireless connection: the ultra dense networks (UDN) paradigm. How to associate users and base stations is one of the most investigated research topics. Many criteria can be drawn, from minimization of power consumption to optimization of throughput. In this paper we propose a new utility to optimize two of the most important features of future mobile connection: security and energy consumption. By using our utility it is possible to jointly select the base station to be activated in a UDN, and associate users to the base stations with the aim of maximizing the secure throughput by spending the minimum energy. Moreover, we propose a heuristic that allows to achieve performance very close to the optimal one with reduced complexity. Effectiveness of the proposed approach is proved by means of comparison with benchmark approaches.
