摘要	Hidden credentials are useful in situations where requests for service, credentials, access policies and resources are extremely sensitive. Current research related to hidden credentials has the shortage that the attribute model cannot provide the complex description. This paper presents a hierarchical hidden credential model which combines the attribute tree structure and the hierarchical identity-based encryption. Attribute tree structure is given that is used to organize sensitive information and the hierarchical hidden credential model is applied to carry and transport credentials, sensitive access control policy, and private resource and so on. This model expands the attribute from a simple atom one to an attribute tree. After the evaluation, it is proven that this model overcomes the shortcomings such as high-load network communication, too many credential exchanges which was caused by attribute-based access control policy. The usability and expansibility of hidden credentials were improved also. © (2012) Trans Tech Publications, Switzerland.; Hidden credentials are useful in situations where requests for service, credentials, access policies and resources are extremely sensitive.
