Abstract :
In this article, a network-level, service-usage solution, which provides assured accounting information strongly bound to the host identity, so that the user is unable to repudiate the charges. To protect the user, the solution employs a granular approach, where evidence of service usage is provided in a piecemeal manner, i.e., pay as you go. An implementation of such a solution is presented, which is based on the employment of host identity protocol (HIP) and hash chains.
