Abstract

We developed a secure processor that protects foreign software running on an open source operating system (OS). The implementation of such a processor has not been reported yet. The processor is called L-MSP (License-controlling Multi-vendor Secure Processor). In this paper, the relationship between software protection and user privacy is discussed. In general, software protection enables secure distributed computing and copyright protection, but the software might violate user privacy. In the L-MSP system, user privacy is able to be protected by security sandbox and related OS mechanisms which is implemented in an open source. Thus transparency of user privacy protection can be assured on the system.
