Abstract:

A technique provides a security-sensitive environment. The technique involves establishing a first secure channel from a trusted server to a first data source D. The technique further involves establishing a second secure channel from the trusted server to a second data source D. The technique further involves, while the trusted server performs a set of collaborative operations in which the trusted server (i) accesses the first data source through the first secure channel (ii) accesses the second data source through the second secure channel, and (iii) generates a set of collaborative results based on information from the first and second data sources (i. e. , the output of f(D,D)), running a set of security policy compliance operations in the trusted server to inhibit unauthorized leakage of data in the set of collaborative results.
