The cloud computing protection in digital library was analyzed, for cloud storage, digital books borrow, and other related issues, a specific application of homomorphic encryption method cloud computing was suggested. First, the cloud computing mode of files digital resources is defined, a variety of collections databases and network resources take on cloud computing mode to give their service, these resources and service are positioned in the cloud. And then the cloud input allocation format to get used to library applications was presented, the developed conventional Public Key Infrastructure, the PKI-based cloud computing message and privacy security mechanisms for annals are introduced. The corresponding solution explained in detail proposed system. Those are library cloud computing key distribution, authentication and encryption methods, homomorphic encryption mechanism for library information recovery. These measures can care for the privacy and information security of library cloud computing.
