Privacy authentication using key attribute-based encryption in mobile cloud computing

TL;DR: RS-IBE provide both forward security and backward security of cipher text by introducing user functionalities and updating of cipherText thereby providing more stability to the hoarded facts.

TL;DR: This study examines students' understanding of cloud computing's advantages, disadvantages, and security issues in Pakistan's higher education sector, revealing a lack of awareness and proposing maximum utilization with ensured security to mitigate potential threats and adverse effects.

TL;DR: This paper proposes the first key-policy attribute-based encryption schemes allowing for non-monotonic access structures (i.e., that may contain negated attributes) and with constant ciphertext size and describes a new efficient identity-based revocation mechanism that gives rise to the first truly expressive KP-ABE realization with constant-size ciphertexts.

TL;DR: The factors affecting Cloud computing adoption, vulnerabilities and attacks are surveyed, and relevant solution directives to strengthen security and privacy in the Cloud environment are identified.

TL;DR: It is shown how new primitives in attribute-based cryptography can be used to construct a secure and privacy-preserving EHR system that enables patients to share their data among healthcare providers in a flexible, dynamic and scalable manner.

TL;DR: In this paper, the authors present archived theoretical, practical, tutorial and survey papers on all aspects of supercomputing, including technology, architecture and systems, algorithms, languages and programs, performance measures and methods, and applications.
