因此，本文基于MA-MEC的物联网，从物理层的角度研究了解决安全威胁的方法，因为物理层安全技术具有实现完全保密性、低计算复杂度和资源消耗以及对信道变化的良好适应性等优点。具体来说，我们研究了安全窃听编码、资源分配、信号处理、多节点协作以及物理层密钥生成和身份验证，以应对新出现的安全挑战。
However, deploying cloud computing capability within the radio access network may face serious security threats, which stem from not only the existing technologies and networks but also the MA-MEC-based IoT itself. Therefore, in this paper, the solutions to address the security threats are investigated from physical layer perspectives, since physical layer security technologies have the advantages of achieving perfect secrecy, low-computational complexity, and resource consumption, and good adaptation for channel changes. Specifically, we investigate the secure wiretap coding, resource allocation, signal processing, and multi-node cooperation, along with physical layer key generation and authentication, to cope with the emerging security challenges. Finally, the paper is concluded with some possible future research directions.

提出了一种基于认知的安全MISO WPT-MEC框架。考虑一个由多天线主发射机（PT）、多天线副基站（SBS）、单天线主接收机（PR）和单天线MD组成的CR网络，SBS作为一个安全的协作中继来提高PT的传输速率，并使用WPT对MD进行充电，从而提前完成PT传输并获得频谱接入机会，以便MD执行MEC。
A secure MISO cognitive-based WPT-MEC framework is proposed. Consider a CR network consists of a multi-antenna primary transmitter (PT), a multi-antenna secondary base station (SBS), a single-antenna primary receiver (PR) and a single-antenna MD. The SBS acts as a secure cooperative relay to improve the transmit rate of the PT and charge the MD using WPT, which could lead to earlier completion of the PT’s transmission and obtain spectrum access opportunities for the MD to execute MEC.

我们提出了一种风险感知计算卸载（RCO）策略
In this paper, we propose a risk-aware computation offloading (RCO) policy
1我们为支持MEC的小型蜂窝网络设计了风险感知计算分流（RCO）。它共同考虑了服务器端攻击所引起的服务延迟和安全风险。
2基于StackelbergGame（边缘系统运营商为领导者，攻击者为追随者），提出了RCO问题，同时考虑了边缘系统运营商和运营商的战略行为。为了应对攻击者行为的不确定性，我们使用贝叶斯Stackelberg游戏框架，在该框架中，边缘运营商无需确切了解其面临的攻击者.
3为了促进推导RCO的Stackelberg平衡，我们提出了两种修剪策略：启发式规则（HP）和分支界限（BaB）。惠普通过分析可能的攻击者类型，用户需求分布和用户边缘可访问性来排除非均衡策略。 BaBuse进行分离式编程，并通过Bender的裁剪以分支和边界的方式创建搜索树。

1. We design a Risk-aware Computation Offloading (RCO)for MEC-enabled small-cell networks. It jointly considersthe service delay and security risk caused by server-sideattacks. The proposed method is cost-efficient and suitable forimmediate deployment.2) The RCO problem is formulated based on the StackelbergGame (the edge system operator acts as the leader and theattacker acts as the follower) by considering the strategicbehavior of both the edge system operator and attackers.To deal with the uncertainty in attackers’ behavior, we usethe Bayesian Stackelberg Game framework where the edgeoperator does not need to know precisely the attacker it faces.3) To facilitate the derivation of the Stackelberg equilibriumof RCO, we propose two pruning strategies: Heuristic Rules(HP) and Branch-and-Bound (BaB). HP works by analyzingpossible attacker types, user demand distribution, and user-edge accessibility to rule out non-equilibrium strategies. BaBuses disjunctive programming and Bender’s cut to create asearch tree by branch-and-bound.4) We run extensive simulations to evaluate the performanceof RCO under various system configurations. The result con-firms that RCO significantly improves the security of MECsystems and the Stackelberg equilibrium can be derived moreefficiently compared to the existing approaches.The rest of this paper is organized as follows. Section IIreviews related works. Section III gives the system modeland problem formulation. Section IV formulates RCO as aStackelberg game and proposes two pruning strategies forderiving the equilibrium. Section VI carries out simulations,followed by conclusions in Section VII.

Therefore, in this study, in addition to proposing a joint load balancing and computation offloading technique for MEC systems, we introduce a new security layer to circumvent potential security issues. First, a load balancing algorithm for efficient redistribution of MDUs among sBSs is proposed. In addition, a new advanced encryption standard (AES) cryptographic technique suffused with electrocardiogram (ECG) signal-based encryption and decryption key is presented as a security layer to safeguard the vulnerability of data during the transmission. Furthermore, an integrated model of load balancing, computation offloading and security is formulated as a problem whose goal is to decrease the time and energy demands of the system. Detailed experimental results prove that our model with and without the additional security layers can save about 68.2% and 72.4% of system consumption compared to the local execution.
