云计算环境下的联盟认证协议

Security has been regarded as one of the hardest problems in the development of cloud computing. This paper proposes an Alliance-Authentication protocol among Hybrid Clouds that include multiple private clouds and/or public clouds. Mutual authentication protocol among entities in the Intra-Cloud and Inter-Cloud is proposed. Blind signature and bilinear mapping of automorphism groups are adopted to achieve the Inter-Cloud Alliance-Authentication, which overcome the complexity of certificate transmission and the problem of communication bottlenecks that happen in traditional certificate-based scheme. Blind key, instead of private key, is adopted for register, which avoids the unauthorized Key Management Center (KMC) faking the members to access the resources in traditional identity-based scheme. Compared with the traditional scheme, our scheme can also achieve anonymity, traceability and privacy protection. Extensive security and performance analysis show that the proposed schemes have an advantage in security, computation consumption and communication consumption.     

基于Godel t-模的模糊Hopfield网络的有效学习算法

神经网络研究的关键问题之一是为神经网络提出有效学习算法。利用t-模的伴随蕴涵算子,为基于Max和TG合成的Hopfield网络Max-TGFHNN提供了一种新的学习算法,此处TG是Godelt-模算子。从理论上严格证明了,只要存在连接权矩阵使得任意给定的模式集成为Max-TGFHNN的平衡态集合,则依该学习算法所确定的连接权矩阵(W$)是所有这样的连接权矩阵中的最大者。并用实验验证该学习算法的有效性。     

基于Camera link接口的双目CMOS APS成像系统的研究
