Blockchain Based Access Control
Access Control systems are used in computer security to regulate the access to critical or valuable resources. The rights of subjects to access such resources are typically expressed through access control policies, which are evaluated at access request time against the current access context. This paper proposes a new approach based on blockchain technology to publish the policies expressing t...
متن کاملVerifiable Attribute Based Encryption
In this paper, we propose the notion of Verifiable Attribute-Based Encryption (VABE) and give two constructs of key-policy VABE. One is with a single authority, and the other is with multi authorities. Not only our schemes are proved secure as the previous ABE schemes, they also provide a verification property. This could not be trivially solved, such as trying random decryption. Adding the ver...
متن کاملBlockchain-based TLS Notary Service
The Transport Layer Security (TLS) protocol is a de facto standard of secure client-server communication on the Internet. Its security can be diminished by a variety of attacks that leverage on weaknesses in its design and implementations. An example of a major weakness is the public-key infrastructure (PKI) that TLS deploys, which is a weakest-link system and introduces hundreds of links (i.e....
متن کاملA Case Study for Grain Quality Assurance Tracking based on a Blockchain Business Network
One of the key processes in Agriculture is quality measurement throughout the transportation of grains along its complex supply chain. This procedure is suitable for failures, such as delays to final destinations, poor monitoring, and frauds. To address the grain quality measurement challenge through the transportation chain, novel technologies, such as Distributed Ledger and Blockchain, can br...
متن کاملA Review of BlockChain
Blockchain is an emerging technology for decentralized and transactional data sharing across a large network of untrusted participants. It enables new forms of distributed software architectures, where components can find agreements on their shared states without trusting a central integration point or any particular participating components. Considering the block- chain as a software connector...
