Epos – an instrument for the assessment of the ethical position in software development

Digital technology becomes more powerful, intelligent, pervasive and ubiquitous. Ethical aspects of this development have not yet drawn the appropriate attention of researchers and engineers. This paper presents an instrument that aims at measuring the individual ethical position with regard to the design and development of computer software. The development of the Epos tool was based on two data collections. The data of the first survey (n₁ = 147 participants) were used to select items and to determine the factorial structure of the questionnaire. Results show that the Epos instrument reliably assesses peoples’ ethical opinion with respect to five central components: (1) regulation, (2) data privacy, (3) domain specific knowledge, (4) societal responsibility and (5) company responsibility. In the second survey, we determined the stability of the instruments factor structure by assessing a sample of n₂?=?196 participants. A confirmatory factor analysis (CFA) supported the initial factor structure. Next steps and further implications are discussed regarding the final version of the questionnaire.

An improved and provable self‐certified digital signature scheme with message recovery

This paper presents a self‐certified digital signature scheme with message recovery that is proven to be secure. So far, many schemes of this kind have been proposed to keep message secret in the transmission. But Zhang et al. has proposed the man‐in‐middle attack to Shao's self‐certified signature scheme, which is based on discrete logarithm. The attacker can make a new signature by using an old one, but the reason of such man‐in‐middle attack was not referred. We present the scheme of Yoon et al., which is also based on discrete logarithm, that cannot resist man‐in‐middle attack either, give the analysis of the attack, and propose a new scheme. The proposed scheme can resist forgery attack in the random oracle model and avoid message leakage, the man‐in‐middle attack, and meanwhile has several security characters. Compared with some self‐certified schemes, our scheme is the best because of the time cost. Copyright © 2013 John Wiley & Sons, Ltd.
