Advances in quantum computers pose great threats on the currently used public key cryptographic algorithms such as RSA and ECC. As a promising candidate secure against attackers equipped with quantum computational power, multivariate public key cryptosystems (MPKCs) have attracted increasing attention in recently years. Unfortunately, the existing MPKCs can only be used as a multivariate signature scheme, and it remains unknown how to construct an efficient MPKC enabling secure encryption. Furthermore, some multivariate signature schemes have been shown insecure in recent years, and it is also not trivial to build MPKC which can serve as a secure signature scheme. By employing the basic MQ-trapdoors, this paper proposes a novel MPKC and shows how it can be used as a multivariate signature scheme and a multivariate encryption scheme, respectively. The goal is achieved by incorporating our new hash authentication techniques and some modification methods such as the Shamir's minus method. Thorough analysis shows that our schemes are secure and efficient. Our MPKC gives a positive response to the challenges in multivariate public key cryptography.

With the rapid development and the richer content of the Internet, the copyright protection of the works should be further developed. The watermarking has become a possible solution. In this paper, firstly, a novel hybrid multiplicative rule is presented and utilized to embed the watermark into DWT coefficients controlled by the secret key. Secondly, the optimum and locally optimum hybrid multiplicative multi-watermarking decoders are proposed, respectively, which are based on the minimum Bayesian risk criterion. The DWT coefficients are modeled as the generalized Gaussian distribution. Nextly, the performance of the optimum hybrid watermarking decoder, i.e. the average bit error rate is theoretically analyzed. Then the security of the hybrid multiplicative watermarking scheme is compared with the existing schemes. Finally, experimental results prove the theoretical analysis valid.

In the mobile agent system, the authentication and identity delegation of mobile agents are the important security problem. This paper focuses on the issues faced by a relying party when deciding to trust a CA and the certificates that it issues. The scope of this paper is limited to examining the basis for trusting a relying party places in an identity certificate signed by a CA. Some of the working group’s discussion of the authentication and delegation of identity of mobile agent are also presented. This paper also gives a way to protect private keys and identity certificates in the mobile agent environment. The mobile agent and agent platform can use these certificates to build trust relationships between the CA and its registration authorities, or trust relationships between the end entities and the service providers.

现实的多停车场资源统一诱导系统中,由于停车硬件厂商、归属、开放时间、收费标准都难以统一,导致系统中停车资源异构、智能计算能力弱、第三方接入困难、安全级别较低等问题。针对这些问题,提出一种基于移动Agent的停车诱导云平台,利用Agent在协作性、共享性、安全性方面的内在优势与云平台的开放性优势相结合。通过建立ParkAgent的结构化层、迁移层、协作层和共享层,有效改进了异构资源统一、异地资源协同、第三方系统安全快速接入问题。在云平台架构下,实现了后台云服务与前端云硬件终端的对接。该系统在苏州城市管理中进行实际应用,优化了停车场资源的分配,显著提高资源利用率,为出行提供了方便。
