Abstract

A benchmarking service is engineered to provide computing performance metric benchmarks based on computing performance metrics provided from a variety of providers without being exposed to the underlying computing performance metrics. A homomorphic encryption scheme is used in a threshold cryptography scenario that allows aggregation of the computing performance metrics without decrypting the metrics. An independent decryption service can partially decrypt the benchmark, which can ultimately be decrypted to plaintext for use by the provider. Bitwise operations can be defined to address error problems, and the bitwise operations can be constrained to a smaller bit size to avoid proliferation of gates.
