摘要：This thesis explores a novel MCPABE (Multimessage Ciphertext Policy AttributeBased Encryption) technique, and make use of the Multimessage Ciphertext Policy AttributeBased Encryption to plan an access manage scheme for distributing scalable media depending on information clients’ attributes (e.g., gender, nationality, age) rather than an clear catalog of the clients’ names. The scheme is flexible and efficient because Multimessage Ciphertext Policy AttributeBased Encryption permits a content supplier to indicate an access strategy and encrypt several messages within one ciphertext like that only the clients whose attributes convince the access method can do ciphertext decryption. Any have, the thesis explores how to defend resource restricted mobile devices by offloading calculation intensive functions to cloud servers while without adjusting data confidentiality.
