This paper presents a right management scheme using secret splitting protocol. Right management schemes combat piracy of proprietary data (such as digital music). In these schemes, encryption has been used and it is essential to protect the keys used in encryption. We introduce a new key protection method in which a secret encryption key is generated using both user's hardware-dependent unique information (such as MAC address) and cryptographically secure random bit strings provided by data owner. This scheme prevents piracy by checking hardware-dependent information during rendering and improves the secrecy of the data by individualizing the encryption key for each data.
