Research of cloud computing security in digital library

The cloud computing security in digital library was analyzed, for the digital books borrow, cloud storage and other related issues, a specific application of homomorphic encryption mechanism about library cloud computing was proposed. Firstly, the cloud computing mode of library digital resources is defined, a variety of collections databases and network resources adopt cloud computing mode to provide their service, these resources and service are placed in the cloud. And then the cloud key distribution scheme to adapt to library applications was presented, the improved traditional PKI, the PKI-based cloud computing communication and privacy protection mechanisms for library are introduced. The corresponding solution detail are proposed also: library cloud computing key distribution, authentication and encryption methods, more secure homomorphic encryption mechanism for library information retrieval. Preliminary analysis indicates that, these measures can protect the privacy and information security of library cloud computing.
