Key management system for WSNs based on hash functions and elliptic curve cryptography
Hamzeh Ghasemzadeh, Ali Payandeh, Mohammad Reza Aref
Due to hostile environment and wireless communication channel, security mechanisms are essential for wireless sensor networks (WSNs). Existence of a pair of shared key is a prerequ…
Multi-layer architecture for efficient steganalysis of Undermp3cover in multi-encoder scenario
Hamzeh Ghasemzadeh
Mp3 is a very popular audio format and hence it can be a good host for carrying hidden messages. Therefore, different steganography methods have been proposed for mp3 hosts. But, c…
Calibrated steganalysis of mp3stego in multi-encoder scenario
Hamzeh Ghasemzadeh
Comparing popularity of mp3 and wave with the amount of works published on each of them shows mp3 steganalysis has not found adequate attention. Furthermore, investigating existing…
A Hybrid DOS-Tolerant PKC-Based Key Management System for WSNs
Hamzeh Ghasemzadeh, Ali Payandeh, Mohammad Reza Aref
Security is a critical and vital task in wireless sensor networks, therefore different key management systems have been proposed, many of which are based on symmetric cryptography.…
Jigsaw Cryptanalysis of Audio Scrambling Systems
Hamzeh Ghasemzadeh, Mehdi Tajik Khass, Hamed Mehrara
Recently it was shown that permutation-only multimedia ciphers can completely be broken in a chosen-plaintext scenario. Apparently, chosen-plaintext scenario models a very resource…
