Access Control Management for Secure Cloud Storage
With the widespread success and adoption of cloud-based solutions, we are witnessing an ever increasing reliance on external providers for storing and managing data. This evolution is greatly facilitated by the availability of solutions typically based on encryption ensuring the confidentiality of externally outsourced data against the storing provider itself. Selective application of encryptio...
متن کاملBlockchain 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...
