TL;DR: A first protocol bridging secure storage and secure computation auditing in cloud and achieving privacy cheating discouragement by designated verifier signature, batch verification and probabilistic sampling techniques is proposed, or SecCloud.

TL;DR: The architecture and unique security and privacy requirements for the next generation mobile technologies on cloud-based IoT are introduced, the inappropriateness of most existing work is identified, and several interesting open problems are suggested with promising ideas to trigger more research efforts in this emerging area.

TL;DR: Another kind of key delegating capability in the scheme is developed and the proposed scheme is proved selective-structure chosen plaintext secure and master key secure without random oracles.

TL;DR: Wang et al. as mentioned in this paper proposed a proxy re-encryption scheme without pairings, in which the proxy can only transform the ciphertext in one direction, and the proposal is secure against chosen ciphertext attack (CCA) and collusion attack in the random oracle model based on Decisional Diffie-Hellman (DDH) assumption over the integer factorization assumption.

TL;DR: This work adds traceability to an existing expressive, efficient, and secure CP-ABE scheme without weakening its security or setting any particular trade-off on its performance.
