We present a multi-level multi-distributor based DRM architecture that facilitates client mobility and propose key management mechanism for this system using Identity-Based Encryption (IBE) and Attribute-Based Encryption (ABE). The encrypted digital content sent by a package server can only be decrypted by the DRM client and is protected from attacks by other parties/servers in the system. Our key management protects the key used to encrypt a digital content during its delivery from the package server to the DRM client, not only from purchasers but also from the distribution servers and the license server. The IBE and ABE enables efficiency gains in computation time and storage over the existing certificate-based Public Key Infrastructure (PKI) based approaches as no certificate management and verification is needed by the entities in the system.
