Abstract
When DRM systems are built on a specific computing platform and a coding algorithm, the interoperability among them will be improbable. For enhanced compatibility, MOSES has been developed such that it has a structure that can be decomposed into independent modules for interoperability with other DRM systems with IPMP functionality. In MOSES, security in contents transaction is provided by JPWallet which controls licenses with key management. In this paper, we present the structure of JPWallet and how the keys are handled between contents servers and contents-consuming clients. The PDA-based codes from the prototype MOSES system have been ported into PC-based codes and tested for compatibility. Analysis of JPWallet, which is the core of MOSES, will contribute to the standardization of domestic IPMP systems compatible with global standards.
