A secure multifactor remote user authentication scheme for Internet of Multimedia Things environment

Parwinder Kaur Dhillon, Sheetal Kalra

Summary To attain ubiquitous connectivity of everything, Internet of Things (IoT) systems must include “multimedia things.” Internet of Multimedia Things (IoMT) is a heterogeneous network of smart multimedia things connected together and with other physical devices to the Internet so as to achieve globally available multimedia services and applications. Due to the ever increasing amount of multimedia data in IoT environments, securing these systems becomes crucial. This is because these systems are easily susceptible to attacks when information or any service is accessed by the users. In this paper, we propose a secure three‐factor remote user authentication scheme for IoMT systems using ECC. The formal security proof performed using ROR model and BAN logic confirms that an attacker will not be able to extract sensitive user information. Through informal security analysis, we justify the resistance of the scheme against several security attacks. The performance comparison shows that the scheme is efficient in terms of computational cost, security features, and attack resistance. Furthermore, simulation of the scheme using AVISPA and Proverif proves that the scheme is secure against all active and passive attacks.

Design and performance analysis of secure optical communication system by implementing blowfish cipher algorithm

Reem A. Hussien, Safa Salam Radhi, Fareed F. Rashid +2 more

With the increasing demand for image transmission in various fields including medical, military and multimedia, the security of information contained on these images has become a standing problem.. This work provides information security for images transfer for 160 Gbps over 140 km optical fiber link. Image encryption and decryption is maintained by applying blowfish algorithm via MATLAB software with the adaption of OptiSystem software to examine data transmission over 16 channels WDM system.. The proposed algorithm has provide a large key space, resistivity to differential attacks, anti-differential attack, brute-force attack and less correlation between adjacent pixels However, channel dispersion and signal attenuation has been controlled with the adaption of symmetric dispersion compensation map and an erbium doped fiber amplifier (EDFA) at the end of the fiber link. Our WDM system design has reached a high figure of merit of about 22,400 as compared with different previous schemes. Moreover, to provoke the power of the proposed cipher algorithm, key space, correlations, histogram analysis and different security analysis has been studied and compared with other algorithms.
