我们考虑建模和设计发布/订阅协议的问题，以保护客户端订阅和服务器发布的隐私，同时保证在具有挑战性的场景下（即实时发布，高数据到达率等）的有效延迟。由于安全功能评估协议理论的一般解决方案在这些场景中无法达到令人满意的性能，因此我们使用第三方（例如云服务器）来丰富模型。我们的主要成果是一个适合于此类场景中的实际应用程序的三方发布/订阅协议，因为发布阶段只使用对称加密操作（没有第三方，结果被认为是不可能的）。我们的协议只会对第三方造成非常小的隐私损失，并且不会对发布服务器或客户端造成隐私损失，因此我们的协议具有非常小的发布延迟，我们在大参数范围内测量的延迟只是一个很小的常数因素，比不保证隐私的发布/订阅协议更差。
We consider the problem of modeling and designing publish/subscribe protocols that safeguard the privacy of clients’ subscriptions and of servers’ publications while guaranteeing efficient latency in challenging scenarios (i.e., real-time publication, high data arrival rate, etc.). As general solutions from the theory of secure function evaluation protocols would not achieve satisfactory performance in these scenarios, we enrich the model with a third party (e.g., a cloud server). Our main result is a three-party publish/subscribe protocol suitable for practical applications in such scenarios because the publication phase uses only symmetric cryptography operations (a result believed not possible without the third party). At the cost of only a very small amount of privacy loss to the third party, and with no privacy loss to the publishing server or the clients, our protocol has very small publication latency, which we measured for large parameter ranges to be just a small constant factor worse than a publish/subscribe protocol guaranteeing no privacy.
