Roaming services in wireless networks provide people with preferable flexibility and convenience. However, such advantages should be offered with both security and privacy in mind. With consideration on privacy protection during roaming in wireless networks, we proposed a hierarchical ID-based roaming protocol in this paper. In our scheme, we use a 2-layer hierarchical ID-based cryptosystem in which a trusted party acts as the root authority, each domain server acts as the second-layer authority, and the roaming user is the end user. With the hierarchical ID-based cryptosystem, we can avoid involvement with home network, and keep the roaming the user's identity private. Furthermore, not only the root authority is relieved from management of a large amount of private/public key pairs, but the domain servers are free to generate key pairs for their registered users. At the same time, we use hash chains together with ID-based signatures to achieve non-repudiation for service payment.
