A Trusted Third Party-Based Key Agreement Scheme in Cloud Computing

摘要

In order to protect authentication information of cloud users transmitted between RPs and OPs, a trusted third party-based key agreement scheme is proposed. In the scheme, encryption card and advanced cipher graph are used to generate one-time encryption key to encrypt one-time process key. The process key is used to encrypt interactive authentication information to prevent it from being leaked out. Analyses show that the scheme is efficient and safe.
