Satisfaction-Maximized Secure Computation Offloading in Multi-Eavesdropper MEC Networks

Abstract

In this paper, we consider a mobile edge computing (MEC)-based secure computation offloading system, and design a practical multi-eavesdropper model including two specific scenarios of non-colluding and colluding eavesdropping. Furthermore, we design a requirement satisfaction model by exploring practical variations in user request patterns for security provisioning, delay reduction and energy saving. Based on these, we propose a satisfaction-maximized secure computation offloading (SMax-SCO) scheme, and then formulate an optimization problem aiming at maximizing users' requirement satisfactions subject to secrecy offloading rate, tolerable delay, task workload and maximum power constraints. Since the optimization problem is nonconvex, we present an efficient successive convex approximation (SCA)-based algorithm to obtain suboptimal solutions. We demonstrate that the proposed SMax-SCO scheme achieves a significant improvement in security performance and requirement satisfaction compared with existing schemes. Moreover, we conclude that SMax-SCO can resist eavesdropping attacks of multiple eavesdroppers and even colluding eavesdroppers.

[Retracted] Analysis and Research on Influencing Factors of College Students’ Satisfaction with Physical Education

“…With the increase of physical education teaching time, the rerepair rate of graduate students and undergraduate students will decline, which indicates that extending teaching time is conducive to reducing the rerepair rate of college students, which is consistent with the existing report conclusion, Mergulhao et al [ 8 ]. The investigation in Northeast China Luo et al [ 9 ], Southeast China Liu et al [ 10 ], West China, and other places also shows that high awareness of physical education can significantly reduce students' restudy rate Liu and Zhuang [ 11 ], so it is very important to carry out effective physical education, Ji et al [ 12 ], which can improve the physical education effect of college students, Hamilton et al [ 13 ]. It is the key to further developing targeted physical education for college students.…”

A comprehensive review on internet of things task offloading in multi-access edge computing

“…The goal of resource allocation is addressed in approximately 10 % of the reviewed literature [ 99 , 103 , 105 , 111 , 116 , 121 ]. In addition, 48 % of the research work focuses on both task allocation and resource allocation issues [ 76 , 80 , 83 , 87 , 89 , 141 , 142 , 144 , 146 , 92 , 95 , 101 , 102 , 107 , [112] , [113] , [114] , [115] , [117] , [118] , [119] , [120] , [122] , [123] , [124] , [126] , [127] , [128] , [129] , [132] , [133] , [134] , [135] , [136] , 148 , 149 ]. The Distribution and overlay of IoT task offloading problems addressed in MEC are shown in Fig.…”

“…A global energy consumption optimization of task offloading based on Lyapunov optimization theory is implemented in Ref. [ 89 ]. In addition, this study also focuses on multi-task parallel offloading for each TD, rather than just offloading multiple computing tasks in a serial sequence manner.…”

International Comparison on the Application of Information Technology in High School Mathematics Textbooks

“…In [27], Bai et al jointly optimized offloading and attacking decisions to maximize the expected reward of the edge system, which involves both the service delay and security risks. In [28], Liu et al jointly optimized task partition, uplink transmission power and offloading rate to maximize the requirement satisfaction of all users, which is quantized as a combination of delay, energy consumption and security decisions.…”
