In secure multicast communication, packet source authentication is a bot-tleneck problem due to the dynamic property of the multicast group, unreliability of datatransmission and the large number of data packets. This paper proposes a novel authentica-tion scheme called B-MSAS (Balance Multicast Source Authentication Scheme) that can beused to solve this problem, in which a new message authentication technique is introduced.This scheme dramatically reduces the signature size overhead and raises the signature rate. Itprovides the non-repudiation service, high loss resistance, and can easily be scaled up to poten-tially millions of receivers, and hence has a sweeping applicability. It should have applicationsto many practical problems.

Based on the Schnorr signature scheme, a new signature scheme with non-repudiation is proposed. In this scheme, only the signer and the designated receiver can verify the signature signed by the signer, and if necessary, both the signer and the designated receiver can prove and show the validity of the signature signed by the signer. The proof of the validity of the signature is noninteractive and transferable. To verify and prove the validity of the signature, the signer and the nominated receiver needn＇t store extra information besides the signature. At the same time, neither the signer nor the designated receiver can deny a valid signature signed. Then, there is no repudiation in this new signature scheme. According to the security analysis of this scheme, it is found the proposed scheme is secure against existential forgery on adaptive chosen message attack.

Fairness is of crucial importance for the exchange protocols via Internet . non-repudiation therefore becomes one of the vital premises, which are essential in the exchange of sensitive and important messages. This paper is to propose a new exchange protocol, termed ＂EAR＂ Exchange Protocol as it consists of three sub-protocols ： Exchange sub-protocol, Abort sub-protocol and Recovery sub-protocol. It is to be argued that the incorporation of these three sub-protocols may effectively enables EAR to assure non-repudiation, strong fairness, timeliness, confidentiality and the minimized involvement of the Trusted Third Party （TTP）.

Ronggong.Song proposed a set of protocols for Pay-TV systems in order to secure the subscribers’ privacy in 2003. In his paper, he developed a new conditional access system (CAS ) mechanism -"e-ticket"- for Pay-TV systems to protect the subscribers’ privacy from abuse by both outsiders and providers, which introduced the combination of the partial blind signature and anonymous digital signature makes Pay-TV systems more robust and fair than before. However, we have found that a dishonest subscriber could abuse the privacy to cheat the Pay-TV systems’ service provider to get more benefits out of his affordability. We analyze the reason and discuss the possible solutions by developing a new mechanism called "subscription token" which remains the characteristics such as strong privacy and non-repudiation.

non repudiation services provide the parties involved in a transaction with protection against the other party by denying that a particular event or action took place. They collect irrefutable evidence to support the resolution of any such disagreement. We address this security issue by first examining the previous work done in this area, and then propose a novel protocol to achieve mutual non repudiation service, encompassing both mandatory evidence of origin and mandatory evidence of receipt. By using two simple ideas, a conditional signature and a public notice board, the novel protocol can achieve this security service in a simple but effective manner. By applying cryptography technology, this protocol also provides privacy for the parties using the security service.

Security testing is a critical concern for organizations worldwide due to the potential financial setbacks and damage to reputation caused by insecure software systems.One of the challenges in software security testing is test case prioritization,which aims to reduce redundancy in fault occurrences when executing test suites.By effectively applying test case prioritization,both the time and cost required for developing secure software can be reduced.This paper proposes a test case prioritization technique based on the Ant Colony Optimization(ACO)algorithm,a metaheuristic approach.The performance of the ACO-based technique is evaluated using the Average Percentage of Fault Detection(APFD)metric,comparing it with traditional techniques.It has been applied to a Mobile Payment Wallet application to validate the proposed approach.The results demonstrate that the proposed technique outperforms the traditional techniques in terms of the APFD metric.The ACO-based technique achieves an APFD of approximately 76%,two percent higher than the second-best optimal ordering technique.These findings suggest that metaheuristic-based prioritization techniques can effectively identify the best test cases,saving time and improving software security overall.

Yoon and Yoo recently proposed a robust authenticated encryption scheme and claimed their scheme has the properties of forward secrecy and confidentiality. The current paper, however, points out that Yoon-Yoo＇s scheme also can not provide forward secrecy and confidentiality such that any adversary can easily recover the transferred message. Based on intractability of reversing the one-way hash function and discrete logarithm problem, an improved authenticated encryption scheme with messages linkage is proposed. The above security faults get solved perfectly. The new scheme is proven to satisfy all the basic security requirements of the authenticated encryption scheme. And by the concrete comparison, it has the similar efficiency of the original scheme.

This paper focuses on the level of adoption of E-Commerce Technology at the Scientific and Industrial Research and Development Centre (SIRDC), a Zimbabwean organization established by an act of parliament, with a mandate to develop, adopt and adapt new technologies for the benefit of Zimbabwean companies and organizations. The study was done in 2004 and the findings reviewed in 2012 with similar results. The objective of the study was to establish whether E-commerce technology adoption would result in the organization being more efficient and effective in delivering its mandate and then establish the level of adoption of the technology at the centre using abstraction and a questionnaire survey. Abstraction results showed that organizations which had fully embraced the technology were more efficient and effective while the survey revealed that the centre had partially adopted the technology. It was recommended that the centre should fully embrace the technology and market it to other organizations as per its mandate.

Service-Oriented Architecture (SOA), which is an open architecture, provides developers with more freedom. However, its security problem goes from bad to worse. By taking an insurance business in Formal Concept Analysis (SOA-FCA) Service Components based Service Data Object (SDO) data model transfer with proxy as an example, the security issue of SDO data model was analyzed in this paper and this paper proposed a mechanism to make sure that the confidentiality, integrity, and non-repudiation of SDO data model are preserved by applying encryption/decryption, digest, digital signature and so on. Finally, this mechanism was developed and its performance was evaluated in SOA-FCA Service Components.
