The Role of SSL/TLS, IPsec & IKEv2 Protocols in Security of E-learning System’s Communications, A Study & Simulation Approach

Authentication and key distribution protocol based on Diffie-Hellman algorithm and physically unclonable function

“…Let us consider the general chart of authentication of a key generated by users А and В if there is a TA under conditions of attacks of an active eavesdropper Е Figure 2. The users communicate with TA, where they are preliminary authenticated using protocols that apply certificates, for example, protocols SSL/TLS or IPSec [23]. The users have integrated PUF blocks into their devices.…”

A New Secure Passwordless Multi-Server Modified Authenticated Master-Key Agreement Scheme Based on Hardware-Software and Iriscode Identifiers Through SSL/TLS Protocol for E-learning and Similar Web-based Services

“…4T EXP +7T SYM +29T h SR: Server Registration Phase, SA: Server Authentication Phase, UR: User Registration Phase, ULA: User Login and Authentication Phase, PC: Password Change Phase, RCA: Registration Center Authentication Phase Table 11: Comparison of execution times with considering (Zivi et al, 2017a), (Chuang and Chen, 2014) and (Chaudhry et al, 2016) for proposed model and other methods Models Execution times (Microsecond) Improvement of proposed method (%) Kim et al (2012) 20237.0 67.09 Yoon and Yoo (2013) 20237.0 67.09 Chuang and Chen (2014) 11357.9 −6.22 Mishra et al (2014) 11376.1 −6.07 Amin et al (2015) 35853 Kim et al, Yoon and Yoo, Chuang and Chen, Mishra et al and Amin et al models, five IKEv2 operations for acquiring the same result is considered. This five IKEv2 operation is for client side configuration: (1) request from the server for client side configuration, (2) respond from the user for applying this configuration, (3) sending configuration script or algorithm for receiving validation message, (4) sending system-level execution permission and (5) sending configuration result.…”

“…Also the IKEv2 task processing time choose from our previous research. This value is average of task processing time in 10%, 30% and 50% of background traffic in 3 states of evaluation (Zivi et al, 2017a) Also Table 9 shows the Security and functional features improvements in percent for proposed model in comparison to other models. To calculate the security percentage of each method, (second column of Table 9), considering 16 security components with a security percentage of 100 (proposed method), with assuming that the security components have an equal importance (Table 8), each security component has a 6.25% impact on overall security.…”

“…The aim of this research was to provide an authentication protocol based on hardware, software and iriscode identifier through a SSL/TLS protocol for the Elearning and other similar web-based systems such that specifically, a sample has been assessed and examined in the Islamic Azad University Electronic Unit (Zivi et al, 2017b) in order to promote the level of privacy, security in the system, protect the student information and maintain optimal function of the system. The reason for using a SSL/TLS protocol in this authentication model has been explained in detail in a previous research (Zivi et al, 2017a). In the previous study, a SSL/TLS protocol was compared with 2 other protocols called IKEv2 and IPsec and in most comparisons the SSL/TLS protocol provided the best result (Zivi et al, 2017a).…”
