Cloud and Edge computing paradigms provide storage and computing services to traditional and internet of Things devices. One computing platform is not suitable to fulfill the requirements of all ioT devices because of their heterogeneity. in this regard, a federation of various computing paradigms has been emerging, in which a user (first party) with an account on one computing platform (second party) can access the services provided by another computing platform (third party federated with the first computing platform). The user needs to authenticate itself with the third-party computing platform which does not have user credentials. This work proposes a transparent and standard-compliant proxy-based federated authentication for solving the third-party authentication problem in federated cloud and edge computing paradigms. Transparency allows cloud and edge operators to deploy this proxy without having to change the existing authentication protocols. Experimental results illustrate that, as compared with the concatenation of authentication protocols in cloud and edge, proxy-based federated authentication of edge-to-cloud and cloud-to-edge can reduce the authentication delay time by 27.7 percent and 37.9 percent, respectively, and it is also standard compliant.

基于代理的联合身份验证：云边缘联合的透明第三方解决方案

云计算和边缘计算范例为传统和物联网设备提供存储和计算服务。一个计算平台由于其异构性，不适合满足所有ioT设备的要求。在这方面，已经出现了各种计算范式的联合，其中在一个计算平台（第二方）上具有帐户的用户（第一方）可以访问由另一个计算平台（与第一计算联合的第三方）提供的服务平台）。用户需要使用没有用户凭据的第三方计算平台进行身份验证。这项工作提出了一种透明且符合标准的基于代理的联合身份验证，用于解决联合云和边缘计算范式中的第三方身份验证问题。透明性允许云和边缘运营商部署此代理，而不必更改现有的身份验证协议。实验结果表明，与云和边缘中的身份验证协议的连接相比，基于代理的边缘到云和云到边缘的联合身份验证可以分别将身份验证延迟时间减少27.7％和37.9％，并且它也是符合标准的。
