This work presents a simple key management scheme for dynamic SQL randomization based on the approach of the SNMPv3 key generation. The original SQL randomization technique based on keyed randomization proxies lacks a mechanism for managing and updating cryptographic keys, which renders the technique vulnerable to the exposure or theft of the keys. Our scheme provides a practical solution to remove...
The urgent issues for automobile, aircraft and trains companies today are how to reduce the time and cost required for developing a new car. CAE(computer aided engineering) has been regarded as an efficient way to solve these issues. Currently, the courseware for CAE is not enough, which limits education and training for this domain. The paper basing on "Web-based e-learning courseware for CAE"...
In view of the increasing number of waste resources and the actuality that information channels and system of reuse is not perfect. The need for integrative information management system and the construction of venous industry information management system is analyzed. The main features of venous industry information management system are summed up. On this basis, a design project about venous and...
In 2004, Das presented a dynamic ID-based remote user authentication scheme using smart cards. Then in 2005, Liao showed that Das et al.'s scheme has some attacks and proposed a slight modification to their scheme to improve the weaknesses of it. This paper, however, will demonstrate that Liao et al.'s scheme has also some security flaws. Therefore, we propose an improved scheme to conquer their weaknesses...
