Design of Crowdsourcing Supply Chain Platform Based on Ontology and Blockchain
IET Communications, Volume 19, Issue 1, January/December 2025.In this paper, a novel crowdsourcing supply chain platform is proposed based on ontology and blockchain. The matching of tasks and candidate workers has been automatically achieved by designing some ontologies and SWRL rules. The quality of the submitted solutions can be effectively evaluated by the proposed improved confidence‐weighted voting ...

Simplified Ciphertext Policy Attribute Based Encryption for Multimedia Applications
Procedia Computer Science, 2020 Abstract In this modern age we generate data from various sophisticated systems and technologies for our personal use, the security and privacy of the data becomes a major concern while sharing it over the cloud platform. The conventional CP-ABE scheme is used to secure different types of data.The CP-ABE uses the access policy in the form of access ...

Modelling a Reliable Multimedia Transmission Approach for Medical Wireless Sensor Networks
IET Cyber-Physical Systems: Theory &Applications, Volume 10, Issue 1, January/December 2025.The process of secret key sharing utilises the sender's public secret key and the receiver's private secret key to generate a shared secret key between the two devices. This same secret key generation method applies to communication between a sensor and a base station, whether in single‐hop or multi‐hop scenarios. Once the secret key is generated, data

Ciphertext-policy hierarchical attribute-based encryption with short ciphertexts
Information Sciences, 2014 10.1016/j.ins.2014.01.035 Attribute-based encryption (ABE) systems allow encrypting to uncertain receivers by means of an access policy specifying the attributes that the intended receivers should possess. ABE promises to deliver fine-grained access control of encrypted data.
