Abstract Three American mathematicians made the NTRU public-key cryptosystem in 1996, it has a fast speed, small footprint, and also it is easy to produce key advantages. The NTRU signature algorithm is based on an integer base, the performance of the signature algorithm will change when the integer base becomes other bases. Based on the definition of “high-dimensional density” of lattice signatures, this paper chooses the ETRU signature algorithm formed by replacing the integer base with the Eisenstein integer base as a representative, and analyzes and compares the performance, security of NTRU and ETRU signature algorithms, SVP and CVP and other difficult issues, the speed of signature and verification, and the consumption of resources occupied by the algorithm.

On March 9, 1995, the Utah Digital Signature Act (the “Utah Act”) was signed into law.1 Complex and ambitious, the Utah Act is intended to promote the use of digital signatures on computer-based documents and to facilitate electronic commerce.2 The Utah Act implements an infrastructure in which computer users utilize “certification authorities,” online databases called repositories, and public-key encryption technology in order to “sign” electronic documents in a legally binding fashion. In addition to setting out a regulatory scheme designed to implement this infrastructure, the Utah Act provides certain digital signatures with legal status as valid signatures and addresses a variety of issues relating to the status of digitally-signed electronic documents in contract and evidence law.

This paper aims to present a number of key challenges to the Jordanian Electronic Government Initiative as a precursor to embracing mobile government (the future electronic governmental service provision). The first wave of electronic governmental services was delivered through the web as the sole communication channel. Despite the limited success of a small number of governmental entities to utilise such a communication channel, the very limited penetration of the Internet in Jordan has dampened such cases of success and pushed key decision makers at the Electronic Government Initiative to consider more popular alternative communication media. This paper reflects on Jordan’s past experience with electronic government to identify lessons learnt to be carried on to future mobile and second wave of electronic governmental service provisions.

The purpose of the article is to assess the accessibility of electronic educational resources (EER) published in the university Moodle Learning Management System (LMS). The analysis involved 22 EERs in mathematical and information technology disciplines, located in the Moodle LMS of the V. I. Vernadsky Crimean Federal University. The examination algorithm included analysis using the Web Accessibility Evaluation Tool (WAVE) and expert analysis of web accessibility using visual, auditory and manual methods based on 89 checklist attributes. In the result of the analysis, multiple accessibility errors of the Moodle platform and the EERs hosted on it were found. The most serious platform problems include: lack of compatibility with text browsers; errors of reproduction by screen readers; errors of content reproduction on mobile devices. The list of accessibility errors made by the authors of EERs includes: incorrect design of hyperlinks (22.7 % of the EERs); lack of subtitles (13.6 %), transcripts (22.7 %), synopses of video lectures (27.3 %); lack of alternative descriptions for figures (68.2 %); time limit for tests (9.1 %); lack of special markup for mathematical notation (36.4 %) and program code (13.6 %), etc. Results of the survey show need in training of EERs’ authors in technologies for developing accessible educational web content. It is advisable to familiarize web developers deploying an LMS at universities with the basics of web accessibility, LMS accessibility functions and modules in order to select the most suitable platform, determine and install the required set of accessibility tools. Before launching all EERs should be subject to mandatory examination for compliance with the web accessibility guidelines.

Electronic government (e-government) resources and websites are a crucial interface for many citizens; yet, accessibility is an often-overlooked attribute when designing such tools. Poorly designed sites can seriously hinder and cause detrimental effects for users relying on these services. How content is presented and delivered on the web makes an impact on how effective and helpful it is, even more so for users with disabilities. This chapter begins with the standards of digital government content presentation and follows up with a look at the compliance rate, current challenges, and possible avenues of future delivery methods. Discussion includes a look at Section 508 and possible update measures to incorporate new devices. This chapter will explore the current drawbacks of automated compliance and accessibility management and provide perspective on what improvements need to be made to foster proper e-government design.

Digital Signature Scheme

A scheme is proposed in this chapter to apply a secure digital signature scheme in a mobile-IP environment and treats the three entities in a dynamic path as either foreign agents (FA), home agents (HA) or mobile agents (MA), such that a coalition is formed containing each of the individual agents. Each agent has a pair of keys: one private and one public. The private key is evolving with time, and the public key is signed by a certification authority (CA). All the private keys of the three agents in the coalition are needed to sign a signature. Furthermore, all the messages are signed and verified. The signature is verified against a public key, computed as the product of the public keys of all three agents, and readily generated when a new dynamic path is formed. In addition, the key-evolving scheme prevents an adversary from forging past signatures under any circumstances. As a result of the schemes’ proactive refresh capability, an adversary must simultaneously compromise each MA, FA and HA in order to forge future signatures. When a new dynamic path is formed or private keys evolve to new states, an interactive, proactive synchronization scheme is employed among the agents. Thus, the loss of a mobile device, or its information, will cause minimal information damage.

This chapter aims to assess the viability of mobile governmental services in Jordan as a precursor to embracing mobile government as a complementing medium of communication. Re?ecting on Jordan’s experience with electronic governmental services, it is evident to say that the ?rst wave of electronic governmental services was delivered through the Web as the sole communication channel. Despite the success of a number of governmental entities to utilise such a communication channel, the penetration of the Internet in the Jordanian society is very low which dampens such limited cases of success. Currently, the e-government initiative is considering mobile phones for the future waves of its electronic service delivery on a multi-channel platform. This chapter articulates the concerns and issues surrounding the viability of mobile government in terms of availability of bandwidth and reach. The chapter will provide a number of statistics and other qualitative reviews concerning previous experiences in the Jordanian electronic government initiative.

The Web

Web Accessibility is a hot topic today. Striving for social inclusion has resulted in the requirement of providing accessible content to all users. However, since each user is unique, and the Web evolves in a decentralized way, little or none is known about the shape of the Web’s accessibility on its own at a large scale, as well as from the point-of-view of each user. In this chapter the authors present the Web Accessibility Knowledge Framework as the foundation for specifying the relevant information about the accessibility of a Web page. This framework leverages Semantic Web technologies, side by side with audience modeling and accessibility metrics, as a way to study the Web as an entity with unique accessibility properties dependent from each user’s point of view. Through this framework, the authors envision a set of queries that can help harnessing and inferring this kind of knowledge from Web graphs.
