The design and evaluation of a cryptography teaching strategy for software engineering students

The present paper describes the design, implementation and evaluation of a cryptography module for final-year software engineering students. The emphasis is on implementation architectures and practical cryptanalysis rather than a standard mathematical approach. The competitive continuous assessment process reflects this approach and rewards experimentation. Students who excel at mathematics will invariably do well in cryptography. A key aim of the module is to try to extend this relationship to include good software engineers who may find mathematics more difficult. The approach is evaluated quantitatively by statistical analysis. The results of the statistical analysis show a significantly higher correlation between a student's performance in software engineering and cryptography than in mathematics and cryptography. These results indicate that this teaching approach is a better fit for software engineers than a standard approach.

Technology and Political Artifacts: The CFP2000 Workshop on Freedom and Privacy by Design

An experimental, all-day Workshop on Freedom and Privacy by Design took place on 4 April 2000, as part of the 10th annual Conference on Computers, Freedom, and Privacy. It invited more than 30 well-known systems architects, implementors, and experts in privacy and usability to investigate, in depth, three different proposals for creating political artifacts: technology intended to bring about particular types of political change--in this case, the reinforcement of certain civil liberties. This article summarizes the rationale and structure of the workshop, the three proposals investigated, and what the workshop and audience members had to say about the issues. It concludes with some information on the workshop's impact to date and what lessons were learned by running such an experiment.     

Improvement of Laih and Yen's multisignature scheme

A new attack is proposed to show that a specified group of verifiers can cooperate to forge the signature for any message by secret key substitution due to the leaked secret key or by the group public key adjustment because of the renewed members. This paper presents the improvement scheme which overcomes the security weakness of Laih and Yen's scheme.
