TLDR
Wang et al. as discussed by the authors proposed a new framework for secure sharing data on cloud-based social networks, which satisfies the security based on the combination of symmetric and asymmetric cryptosystems.Abstract:
In this paper, we propose a new framework for secure sharing data on cloud-based social networks. The framework satisfies the security based on the combination of symmetric and asymmetric cryptosystems. In addition, dynamic one-time used symmetric cryptographic keys and proxy re-encryption schemes are used in this framework to improve the security of cryptographic systems. By using this framework, the data is being shared between users in much more secure way.read more

Improving security and efciency for encrypted data sharing in online social networks
TL;DR: This paper proposes a secure data sharing scheme in OSNs based on ciphertext-policy attribute-based proxy re-encryption and secret sharing that allows users to customize access policies of their data and then outsource encrypted data to the OSNs service provider.

An evaluation of user importance when integrating social networks and mobile cloud computing
TL;DR: A RFTRS scheme is proposed, which innovatively considers the Reputation, Fractal, and Topological importance in SNs as well as the Request and Storage importance in MCC to evaluate user importance to explore the user importance evaluation issue during the integration of SNs and MCC.

Speeding up privacy preserving data mining techniques
TL;DR: An incremental privacy preserving data mining protocol for association rule mining that allows parties to perform mining tasks on updated data instead of entire data called CSSP is proposed and conducted to show the efficiency of the protocol over the existing methods.

Encrypted data sharing with multi-owner based on digital rights management in online social networks
TL;DR: A digital rights management (DRM) scheme is proposed for encrypted data in OSNs that presents a multiparty access control model based on identity-based broadcast encryption and ciphertext-policy attribute-based proxy re-encryption, which enables multiple owners, such as tagged users who appear in a single data, customize the access policy collaboratively.

Multiparty Access Control of Ciphertext Sharing in Cloud-Based Online Social Networks
TL;DR: This paper proposes a ciphertext sharing scheme in cloudbased OSNs, which allows the users to outsource encrypted data to the OSNs service provider for sharing and presents a multiparty access control model based on ciphertext-policy attribute-based proxy reencryption, which enables the access control of encrypted data associated with multiple users.

A public key cryptosystem and a signature scheme based on discrete logarithms
TL;DR: A new signature scheme is proposed, together with an implementation of the Diffie-Hellman key distribution scheme that achieves a public key cryptosystem that relies on the difficulty of computing discrete logarithms over finite fields.

Towards security in sharing data on cloud-based social networks
TL;DR: A framework that allows users of cloud-based social networks to share their private data in a secure manner by using proxy re-encryption schemes and every user in a group has his own secret key to encrypt and decrypt data.
