A security analysis of email communications

The objective of this report is to analyse the security and privacy risks of email communications and identify technical countermeasures capable of mitigating them effectively. In order to do so, the report analyses from a technical point of view the core set of communication protocols and standards that support email communications in order to identify and understand the existing security and privacy vulnerabilities. On the basis of this analysis, the report identifies and analyses technical countermeasures, in the form of newer standards, protocols and tools, aimed at ensuring a better protection of the security and privacy of email communications. The practical implementation of each countermeasure is evaluated in order to understand its limitations and identify potential technical and organisational constrains that could limit its effectiveness in practice. The outcome of the above mentioned analysis is a set of recommendations regarding technical and organisational measures that when combined properly have the potential of more effectively mitigating the privacy and security risks of today's email communications.JRC.G.6-Digital Citizen Securit

MANUAL AND AUTOMATED CONTENT INTERLINKING IN A DYNAMIC WEBPAGE

In this article different ways of linking web pages are described using manual and automated content balancing procedures. SEO techniques are also used for better page interlinking with added value given by the new web standard 3.0 that stands on web semantics.web semantics, S.E.O., interlinking, Web3.0

EDI - XML Standards and Technologies in the Agri-Food Industry

Due to globalisation, the new technological developments and the complexity of food supply processes, the European food sector is increasingly becoming more complex. The consumers’ trust in food, triggered and affected by a number of food crises, is low. Today, consumers increasingly expect safe and high quality food and demand information about the origin of their food. Also, the economic health of the food industry can be greatly affected by food crises; therefore, efficient and effective mechanisms are required to assist the food industry in tracking and tracing products along the food chain. In this paper, we discuss the criteria for an efficient and effective traceability system from an IT perspective (mainly data exchange) and we identify key requirements for ICT enabled traceability

Web browser for delay-tolerant networks

Due to growth of the Internet, the number of devices increasing and the structure of networks becoming more complex, the problem of time delays during information transmissions has arisen. In environments with long transmission delays modern protocols may become inefficient or even useless. Delay-tolerant Networking (DTN) is one approach that allows to solve the problem of long transmission delay times. In the thesis, an approach to web access in such networks is proposed. The problem of data transmission in the networks with long delays is considered. Special methods exist for data transmission in computer networks. But traditional data transmission protocols do not work well in networks with long delays, e.g. when transmitting over long distances, such as in space, or when connectivity may be disrupted, such as in mobile networks. It is necessary, therefore, to replace TCP and to change the existing web protocol (Hypertext Transfer Protocol - HTTP) in order to allow HTTP data transmissions in DTN environments. In the thesis, HTTP is analyzed and an adaptation of HTTP to DTN environments, as proposed in earlier research, is reviewed and extended further. A client part is created and the implementation is described. The client allows solving the problem of HTTP over DTN usage. An open-source browser is modified and the necessary extensions are developed. The extensions allow to use the DTN transport protocol (i.e. the Bundle Protocol) as another option of transport other than TCP. The software module for a web browser is built on the Mozilla platform. It was shown that it is possible to create a browser to work in DTNs

Multi-Media Mail in heterogeneous Networks

The MIME approach seems to be the most reasonable effort for allowing the sending and receiving of multimedia messages using standard Internet mail transport facilities. Providing new header fields, such as MIME-Version, Content-Type, and Content- Transfer-Encoding, it is now possible to include various kinds of information types, e.g. audio, images, richtext, or video, into a RFC 822-conformant mail. Making use of these headers, it is possible to fully describe an attached body part, so that a receiving mail user agent is able to display it without any loss of information. Additionally, the definition of the "multipart" and "message" content types allows the creation of hierarchical structured mails, e.g. a message containing two alternative parts of information, one that can be shown using a simple ASCII-terminal, the other to be displayed on a multimedia workstation. Allowing the definition of bilaterally defined content types and providing a standardized means of establishing new content types prevent MIME from being a one-way road and supply mechanisms to extend MIME for future use

Automatic generation of audio content for open learning resources

This paper describes how digital talking books (DTBs) with embedded functionality for learners can be generated from content structured according to the OU OpenLearn schema. It includes examples showing how a software transformation developed from open source components can be used to remix OpenLearn content, and discusses issues concerning the generation of synthesised speech for educational purposes. Factors which may affect the quality of a learner's experience with open educational audio resources are identified, and in conclusion plans for testing the effect of these factors are outlined
