Secure Hashing Algorithms (SHA) showed a significant importance in today’s information security applications. The National Institute of Standards and Technology (NIST), held a competition of three rounds to replace SHA1 and SHA2 with the new SHA-3, to ensure long term robustness of hash functions. In this paper, we present a comprehensive hardware evaluation for the final round SHA-3 candidates. The main goal of providing the hardware evaluation is to: find the best algorithm among them that will satisfy the new hashing algorithm standards defined by the NIST. This is based on a comparison made between each of the finalists in terms of security level, throughput, clock frequancey, area, power consumption, and the cost. We expect that the achived results of the comparisons will contribute in choosing the next hashing algorithm (SHA-3) that will support the security requirements of applications in todays ubiquitous and pervasive information infrastructure.

How Secure Having IoT Devices in Our Homes?

Journal of Information Security 2020年第2期11卷 81-91页

Nowadays, technology has evolved to be in our daily lives to assist in making our lives easier. We now have technology helping us in our lives at home. Devices used to create our “smart home” have done a great deal in making our lives at home less burdensome, but sadly, these devices have secured our personal lives to be more accessible to outsiders. In this paper, the security of home smart devices and their communication will be researched by using other academic articles to support facts found. The operation of the devices will be discussed along with security risks and future trends on security attacks. The results found will be crucial to knowing exactly how well our own home is protected. After understanding where the risks lie and a demonstration of how hackers can take control of our smart home, solutions will be given to shield ourselves from security attacks. We protect our homes from physical threats by locking doors, but it is time we guard ourselves from cyber threats as well.

C3SM: Information Assurance Based on Cryptographic Checksum with Clustering Security Management Protocol

Journal of Information Security 2012年第4期3卷 272-280页

Wireless Sensor Networks (WSNs) are resource-constrained networks in which sensor nodes operate in an aggressive and uncontrolled environment and interact with sensitive data. Traffic aggregated by sensor nodes is susceptible to attacks and, due to the nature of WSNs, security mechanisms used in wired networks and other types of wireless networks are not suitable for WSNs. In this paper, we propose a mechanism to assure information security against security attacks and particularly node capturing attacks. We propose a cluster security management protocol, called Cryptographic Checksum Clustering Security Management (C3SM), to provide an efficient decentralized security management for hierarchal networks. In C3SM, every cluster selects dynamically and alternately a node as a cluster security manager (CSM) which distributes a periodic shared secrete key for all nodes in the cluster. The cluster head, then, authenticates identity of the nodes and derive a unique pairwise key for each node in the cluster. C3SM provides sufficient security regardless how many nodes are compromised, and achieves high connectivity with low memory cost and low energy consumption. Compared to existing protocols, our protocol provides stronger resilience against node capture with lower key storage overhead.
