摘要： 针对网络应用中用户频繁注册、多账号多密码和反复登录的问题，该文提出了网络用户漫游机制，构造了相应的网络用户漫游模型。引入了漫游信任度、对等实体综合信任度、网络用户信任度来描述实体的可漫游性，给出了各个信任度的计算算法，讨论了网络用户漫游技术。分析和验证表明，基于信任度的对等实体间的网络用户漫游机制具备可行性。

Abstract: This paper puts forward a roaming mechanism of network user to solve the problem that users register and logon frequently using multiple accounts and passwords in network applications and constructs a relevant roaming model of network user. It imports roaming trust degree, integrated trust degree of peer entity, and trust degree of network user to depict entity roaming ability, and gives calculation algorithm of all the trust degrees. It also discusses roaming technology of network user based on the theory. Analysis and verification imply that the roaming mechanism of network user between peer entities based on trust degree is feasible.

Key words: peer entity(PE), peer group(PG), network user roaming, trust degree
