In this paper, we propose a methodology to enhance the evaluation tools in semantic learning systems. Our proposal’s aim is to evaluate two types of open questions in hybrid exams. The proposed technique in the first type MOQ (Multi Operations Question) uses the matrix concept for fuzzy score. But POQ (Proof Open Question) is more complicated so we use(More)
RC4 is the most widely used stream cipher algorithm. It is used to protect valuable electronic information. However , RC4 encryption algorithm suffers from a secret key generation as a seed problems. This paper proposes an intelligent dynamic secret key generation as a seed by employing an Evolutionary Algorithm (EA). The proposed RC4-EA method tends to(More)
Most authentication schemes are using physical token such as smart cards to restrict services. Although these schemes have been widely deployed for various kinds of daily applications; there are severe challenges regarding their infrastructure requirements and security. This paper proposes an efficient authentication protocol based on user's(More)
