Beyond Yao's Millionaires: Secure Multi-Party Computation of Non-Polynomial Functions
Seyed Reza Hoseini Najarkolaei, Mohammad Mahdi Mojahedian, Mohammad Reza Aref
In this paper, we present an unconditionally secure -party comparison scheme based on Shamir secret sharing, utilizing the binary representation of private inputs to determine t…
Using Blockchain to Achieve Decentralized Privacy In IoT Healthcare
Sajad Meisami, Mohammad Beheshti-Atashgah, Mohammad Reza Aref
With the advent of the Internet of Things (IoT), e-health has become one of the main topics of research. Due to the sensitivity of patient information, patient privacy seems challe…
HUAP: Practical Attribute-based Access Control Supporting Hidden Updatable Access Policies for Resource-Constrained Devices
Mostafa Chegenizadeh, Mohammad Ali, Javad Mohajeri +1
Attribute-based encryption (ABE) is a promising cryptographic mechanism for providing confidentiality and fine-grained access control in the cloud-based area. However, due to high…
PKC-PC: A Variant of the McEliece Public Key Cryptosystem based on Polar Codes
Reza Hooshmand, Masoumeh Koochak Shooshtari, Mohammad Reza Aref
Polar codes are novel and efficient error correcting codes with low encoding and decoding complexities. These codes have a channel dependent generator matrix which is determined by…
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…
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.…
