In the past few years, the number IoT devices has increased exponentially and different devices have different requirements due to heterogeneity. Hence, one computing platform is not suitable to fulfill the requirements of all IoT devices. In this case, federation of different computing paradigms comes into play where a user or a device having an account on one computing platform can access the services provided by the other computing platform, federated with the first computing platform, without having to create another account. There are multiple research problems which arise due to the federation among which authentication is the most important one. This work addresses the third-party authentication problem in federated cloud and 3GPP edge systems where a user (first party) having an account on the cloud or edge (second party) needs to access services in the edge or cloud (third party). Related studies in the literature solve these issues by proposing new protocols or by adding new components in the 3GPP system. In this study, we propose the standard-compliant third-party authentication approach, which is the combination of the existing authentication protocols in the cloud and the 3GPP network. we use a federated proxy between cloud and the 3GPP network to solve the problem of message mismatch in the authentication protocols of cloud and edge. The experimental results illustrate that, as compared with the combination of OpenID Connect and EPS-AKA, third-party authentication of edge-to-cloud and cloud-to-edge using federated proxy can reduce the authentication delay time by 27.7% and 37.9% respectively and it is also standard compliant.Ying-Dar Linydlin@cs.nctu.edu.twDuc Tai Truongtaitd95@gmail.comYuan-Cheng Lailaiyc@cs.nctu.edu.twChiYu Lilichiyu@gmail.comAsad Aliali.eed06g@nctu.edu.twThi Thai Mai Dinhdttmai@vnu.edu.vn2020-07-29T08:14:46Z2020-07-29T08:15:17Zhttp://eprints.uet.vnu.edu.vn/eprints/id/eprint/4030This item is in the repository with the URL: http://eprints.uet.vnu.edu.vn/eprints/id/eprint/40302020-07-29T08:14:46ZPerformance of OFDM Based Advanced Encryption StandardCurrently, there are a lot of secure communication schemes have been proposed to hide secret contents. In this work, one of the methods deploying encryption to cipher data is represented. The primary object of this project is applying Advanced Encryption Standard (AES) in communications based Orthogonal Frequency Division Multiplexing (OFDM). This article discusses the security of the method encrypting directly QAM symbols instead of input bit-stream. This leads to improving the security of transmitting data by utilization of authentication key between the mobile and base station. The archived results demonstrate that the performance of the AES-OFDM system is completely acceptable to compare with the criteria for 4G.Duc Tai TruongQuoc Tuan Nguyentuannq@vnu.edu.vnThi Thai Mai Dinhdttmai@vnu.edu.vn
