基于区块链的云身份管理信任模型设计

Design of Cloud Identity Management Trust Model Based on Blockchain

安全可靠的身份管理已成为当今云计算面临的最大挑战之一。目前,身份管理是克服上述问题和简化用户体验的最有用的解决方案,它允许有效的身份验证机制和使用跨多个域分布的数据中的身份信息。这种方式面对新的问题依然不够成熟,比如在管理云服务提供商和其客户机的信任关系方面,会衍生相当多的复杂因素,这是能够改善的。其实许多安全、隐私和互操作性问题就是身份管理系统中的信任管理不善导致的,这会导致组织拒绝将其关键身份数据传输到云中。通过引入一种新的身份管理模型和基于区块链的信任,并可以有效解决这些问题,同时,该身份管理模型用于云身份管理,也能够改善一定的安全性和隐私性。

Establishing secure and reliable identity management has become one of the biggest challenges facing cloud computing today.This is mainly because the model generates a large number of new cloud based applications,which means that more user accounts,passwords and personal information need to be provided,monitored and protected.At present,identity management is the most useful solution to overcome the above problems and simplify the user experience.It allows effective authentication mechanisms and the use of identity information in data distributed across multiple domains.However,this approach creates considerable complexity in managing trust relationships between cloud service providers and their clients.The trust management in the identity management system is not good,which will bring many security,privacy and interoperability problems,which leads to the organization’s unwillingness to move its key identity data to the cloud.This paper aims to solve these problems by introducing a new blockchain based trust and identity management model,which is used for cloud identity management and improves security and privacy.
