针对云计算环境中图书馆外包数字资源的安全展开研究,旨在寻找外包数字资源完整性检测的方法。通过引入密码学和信息安全领域数据完整性检测的最新技术,在数字图书馆领域首次提出支持公开和隐私外包资源的完整性检测方案,方案支持公开验证和隐私数据的保密。理论推导和实验同时证明方案的正确和可行。
The security of the libraries' outsourced digital resources are studied in the environment of cloud computing, with the aim to find ways for integrity verification of those outsourced resources. By introducing the state-of-art technologies belonging to the field of cryptology and information security into the field of digital library, two integrity verification protocols are first proposed for the public and private outsourced digital resources respectively. Both protocols support public integrity verification and protection of private resources. Proofs of correctness and feasibility are given by both theoretical derivations and experiments.
