安全漫游协议允许漫游用户..访问外国服务器..并以认证的方式建立会话密钥，使得.认证..同时也说服了...它是某个服务器H的合法订户，该服务器H被称为U的归属服务器。常规方法需要所有三方的参与。在本文中，我们提出了一种新的方法，只需要两个方面，U和V，参与。我们提出了两个协议：一个提供更好的效率，并支持用户匿名到与当前移动的系统所提供的程度相当的程度;另一个实现了强用户匿名，其保护U的身份不受窃听者和外国服务器的影响，并且是当前为安全漫游定义的用户匿名的最强概念。这两种协议都是通用的，因为无论在哪个域（本地或外地），都使用相同的协议和信令流。是来访的。这有助于在实践中降低系统复杂性。我们还提出了一个实用的用户撤销机制，这是最具挑战性的问题之一，双方漫游支持强用户的Anciliity。我们的解决方案可应用于各种漫游网络，如蜂窝网络和互连无线局域网。
A secure roaming protocol allows a roaming user.. to visit a foreign server.. and establish a session key in an authenticated way such that.. authenticates.. and at the same time convinces.. that it is a legitimate subscriber of some server H, called the home server of U. The conventional approach requires the involvement of all the three parties. In this paper, we propose a new approach which requires only two parties, U and V, to get involved. We propose two protocols: one provides better efficiency and supports user anonymity to an extent comparable to that provided by current mobile systems; and the other one achieves Strong User Anonymity that protects U's identity against both eavesdroppers and foreign servers and is currently the strongest notion of user anonymity defined for secure roaming. Both protocols are universal in the sense that the same protocol and signaling flows are used regardless of the domain ( home or foreign) that.. is visiting. This helps reducing the system complexity in practice. We also propose a practical user revocation mechanism, which is one of the most challenging problems for two-party roaming supporting Strong User Anonymity. Our solutions can be applied in various kinds of roaming networks such as Cellular Networks and interconnected Wireless Local Area Networks.
