Recent years have shown a huge growth in technology, which led to an explosive growth in the volume of data which is referred to as “Big Data”. Wireless sensors are considered one of the highly anticipated contributor to big data nowadays, therefore, avoiding misleading or forged data gathering in case of sensitive and critical data through secure communication is vital. This can be achieved though...
Though many Information Assurance (IA) educators agree that hands-on exercises and case studies improve student learning, hands-on exercises and case studies are not widely adopted due to the time needed to develop them and integrate them into curriculum. Under the support of National Science Foundation (NSF) Scholarship for Service program, we implemented two faculty development workshops to disseminate...
The security flaws of a direct anonymous attestation scheme proposed by He et al. was analyzed, and the result shows that the authentication protocol of the scheme is vulnerable to reply attacks and platform masquerading attacks when being used for remote attestation. An improved direct anonymous attestation authentication scheme with the involvement of key agreement was proposed to provide the property...
To further improve the urban and rural medical assistance system and make it much more convenient in the emergent case, we designed and developed a real-time medical assistance billing system for Linchuan county civil affairs bureau. This system consists of two medical assistance models, one of which is real-time assistance model that realizes a “seamless combination” of the civil affairs assistance...
S-box (Substitution box) is one of the most important components in the block cipher. In this paper, the main indices to evaluate S-box are firstly introduced. Then an algorithm for obtaining cryptographical strong S-boxes based on chaotic neural network is proposed. The chaotic neural network used to design S-boxes is composed of two layers, which have sixteen and eight neurons, respectively. Owing...
By adding a wireless sensor network into a health monitoring system, I have found a method by using the combination of ZigBee and wireless LAN architecture to realize a remote medical monitoring system. The system's nodes and base stations use the short range communication standard: 802.15.4 / ZigBee standard. This system can collect various information from patients, achieving the remote medical...
Quantum no-key protocol is a quantum realization of Shamir's idea of no-key cryptosystem, which can be used to transport quantum and classical message secretly. It is beyond computational security. We give a practical quantum no-key protocol with mutual identification. In order to prevent MIM (man-in-the-middle) attack, we realize secure information transmission and identification by utilizing a short...
The development of e-commerce speeds up on-line commodity circulation, so safe and efficient conduct of electronic payment has become a biggest problem which needs to be solved urgently. In this paper, a scheme of dynamic group blind signature based on elliptic curve discrete logarithm problem is adopted. And at the basic of this scheme, a security model of group blind signature based on elliptic...
