TLDR
A policy-based de-duplication proxy scheme to enable different trust relations among cloud storage components, de- duplication related components and different security requirements is proposed and a key management mechanism to access and decrypt the shared de- DUplicated data chunks based on Proxy Re-encryption algorithms is proposed.Abstract:
Reducing the amount of data need to be transferred, stored, and managed becomes a crucial for cloud storage. On the other hand, as user data are stored and processed by outsourced cloud provider, encryption becomes a necessary before updating data into the cloud. However, the above two goals are greatly opposed to each other. In order to solve the above conflict, a policy-based de-duplication proxy scheme is proposed in this paper. It suggests a policy-based de-duplication proxy scheme to enable different trust relations among cloud storage components, de-duplication related components and different security requirements. Further proposes a key management mechanism to access and decrypt the shared de-duplicated data chunks based on Proxy Re-encryption algorithms. This paper finally analyses the security of the scheme.read more

Summary cache: a scalable wide-area web cache sharing protocol
TL;DR: This paper demonstrates the benefits of cache sharing, measures the overhead of the existing protocols, and proposes a new protocol called "summary cache", which reduces the number of intercache protocol messages, reduces the bandwidth consumption, and eliminates 30% to 95% of the protocol CPU overhead, all while maintaining almost the same cache hit ratios as ICP.

Divertible protocols and atomic proxy cryptography
TL;DR: A definition of protocol divertibility is given that applies to arbitrary 2-party protocols and is compatible with Okamoto and Ohta's definition in the case of interactive zero-knowledge proofs and generalizes to cover several protocols not normally associated with divertibility.
