Abstract :
In this paper, we introduce a novel way to solve the tradeoff problem about communication/storage/computation overhead of broadcast encryption scheme. We construct a new scheme based on subset difference (SD) scheme, use concept of RSA accumulator and the idea of separating the user-side device into different function parts, take advantage of the public device´s functionality, minimize the storage and computation overhead of the private device, and make the broadcast encryption scheme more implementation-oriented.
