摘要: A private stream aggregation (PSA) system contributes a user's data to aggregator without compromising the privacy. The can begin by determining (302) key for local user in set of users, wherein sum keys associated with users and is equal zero. also selects values user. Then, encrypts individual based part on produce encrypted values, thereby allowing decrypt an aggregate value across decrypting interacting while value. sends (308) aggregator.
