Comparative Analysis of Formal Model Checking Tools for Security Protocol Verification
TL;DR: An overview of different formal methods and tools available for security protocol verification is given and one of the more suitable is the Formal approach.
Journal ArticleDOI
A New Secure and Lightweight Searchable Encryption Scheme over Encrypted Cloud Data
Shahzaib Tahir,Sushmita Ruj,Yogachandran Rahulamathavan,Muttukrishnan Rajarajan,Cornelius Glackin +4 more
TL;DR: A novel searchable encryption scheme for the client-server architecture that exploits the properties of the modular inverse to generate a probabilistic trapdoor which facilitates the search over the secure inverted index table is presented.
Proceedings ArticleDOI
A Lightweight Blockchain Based Two Factor Authentication Mechanism for LoRaWAN Join Procedure
Syed Muhammad Danish,Marios Lestas,Waqar Asif,Hassaan Khaliq Qureshi,Muttukrishnan Rajarajan +4 more
TL;DR: The proposed blockchain based framework provides an extra layer of security for LoRaWAN join procedure and build trust among LoRa WAN network components and demonstrates that the proposed framework provides efficient system performance in terms of throughput and latency.
Journal ArticleDOI
Robust access control framework for mobile cloud computing network
TL;DR: Inclusion of dynamic attributes in smart devices such as unlock failures, application usage, location and proximity of devices can be used to determine the risk level of an end-user and this paper seamlessly incorporate the dynamic attributes to the conventional access control scheme.
Proceedings ArticleDOI
Data-centric Rogue Node Detection in VANETs
TL;DR: This paper develops and simulates a technique to detect a rogue node that is sending false emergency messages in VANets by cooperative exchange of data without the need of any infrastructure or revocation list, which will make VANETs fault tolerant and resilient against injection of false data.
