Linkable Spontaneous Anonymous Group Signature for Ad Hoc Groups
TL;DR: A linkable ring signature scheme was proposed in this article, which satisfies the following three properties: anonymity, signer indistinguishability, and linkability: that two signatures by the same signer can be linked.
Journal ArticleDOI
Toward efficient and privacy-preserving computing in big data era
TL;DR: The general architecture of big data analytics is formalized, the corresponding privacy requirements are identified, and an efficient and privacy-preserving cosine similarity computing protocol is introduced as an example in response to data mining's efficiency and privacy requirements in the big data era.
Journal ArticleDOI
An Efficient File Hierarchy Attribute-Based Encryption Scheme in Cloud Computing
TL;DR: An efficient file hierarchy attribute-based encryption scheme is proposed in cloud computing that combines layered access structures into a single access structure, and then, the hierarchical files are encrypted with the integrated access structure.
Journal ArticleDOI
A Secure Cloud Computing Based Framework for Big Data Information Management of Smart Grid
TL;DR: The main idea of the framework is to build a hierarchical structure of cloud computing centers to provide different types of computing services for information management and big data analysis in smart grids, which is called “Smart-Frame.”
Proceedings ArticleDOI
Malicious KGC attacks in certificateless cryptography
TL;DR: Wang et al. as discussed by the authors proposed new security models that remove this assumption for both certificateless signature and encryption schemes and showed that a class of certificateless encryption and signature schemes proposed previously are insecure.
