An ECC-Based Blind Signcryption Scheme for Multiple Digital Documents

The popularity of the Internet has comprehensively altered the traditional way of communication and interaction patterns, such as e-contract negotiations, e-payment services, or digital credential processes. In the field of e-form systems, a number of studies investigate the ability of the blind signature to fulfill the basic properties of blindness and untraceability. However, most literatures exploring the blind signature mechanisms only address research and technology pertaining to single blind signature issues. Further, most of the topics only deal with signing rather than encryption. Thus, we propose a new blind signature scheme for multiple digital documents based on elliptic curve cryptography (ECC). Our scheme incorporates the design of signcryption paradigm into the blind signature scheme to strengthen high levels of security. This innovative method also enhances computational efficiency during processing multiple electronic documents since the ECC provides a shorter key length and higher processing speed than other public-key cryptosystems on equivalent secrecy. The analysis results show that the present scheme achieves better performance at low communication overheads as well as with higher level of security. By helping the design of the intrinsic properties, the proposed cryptosystem can be applied to many areas to protect sensitive data in ubiquitous computing environments.

Augmented Reality Interfaces for Smart Objects in Ubiquitous Computing Environments

It is the goal of ubiquitous computing (UbiComp) to hide computers from the users. Instead, everyday objects embedded with computer processing capability become smart objects that act as interfaces to computer software. A challenge with this new paradigm of computing is to create natural and obvious ways for people to interact with objects and receive output from the computer software that these objects serve as interfaces to. In this chapter, a solution is proposed whereby virtual user interfaces are added to smart objects. These virtual interfaces are viewed in augmented reality through personal viewing devices which also allow people to interact directly with them. The implementation of UbiComp environments and personal viewing devices is described in order to illustrate the use of current technology in creating user-friendly UbiComp environments.
