“…From then on, some other schemes [14] [15] [16] [17] [18] [19] were presented in succession, but they all have some flaws (see table 1). Besides, M Holbl's protocol [15] and N. Liang's protocol [14] have more computation cost. This paper proposes an improved identity based authenticated key agreement protocol which is based on Yuan Li's protocol and Smart's protocol.…”

“…The passwords used to be [14][15][16] and still are the main method of authentication [17][18][19], although research continues on more sophisticated methods of authentication, see e.g. [20][21][22][23][24][25][26][27][28][29]. Some novel solutions are even improvements of concepts well known to the automobile industry (i.e.…”

Background: Recently, Cipresso et al proposed a novel method for generating textual passwords. The PsychoPass password can be created, memorized and recalled by thinking of an action sequence instead of a string of characters.Objective: The objective of this paper is to analyze how and when the PsychoPass passwords are resilient to brute force attacks and how they compare to randomly generated ones.Methods: The PsychoPass method was studied analytically. The number of possible different passwords that can be created using PsychoPass method was calculated for different possible settings.Results: The PsychoPass generates passwords that are resilient to brute force attacks with password lengths comparable to those generated randomly. A PsychoPassgenerated password with 18 characters is as strong as a completely randomly generated password of length 11 characters with mixed upper and lowercase letters, numbers and symbols, but can easily be remembered. Conclusion: The PsychoPass method is an alternative to the existing passwords and is resilient to brute force attack.There is no known dictionary to enable the dictionary attack. The PsychoPass passwords look like random ones, eg. »aEy|dX%7Tu]6hJ«, but a user can easily remember it based on the action sequence instead of remembering its characters.

Abstract-Information technology brought radical changes in various aspects of contemporary life and education sector in general and in higher education in particular. Our institute (Isra University) decided to be more responsive to these dramatic changes and effectively employ information technology to improve the quality of teaching and learning through a gradual shift from web-enhanced courses towards blended learning, distance learning, and open learning to achieve better learning outcomes excellence and competition. We uses Moodle system to offer web-enhanced courses with timed on-line quizzes as well as a vehicle for students to submit homework assignments and gain access to different course related resources. This paper investigates the risks encountered at Isra university e-learning system (IUELS) in the offering of web-enhanced courses and how we solved the problems.
