Identifying a cluster around a seed node in a graph, termed local clustering, finds use in several applications, including fraud detection, targeted advertising, community detection, etc. However, performing local clustering is challenging when the g

Mixing arithmetic and boolean circuits to perform privacy-preserving machine learning has become increasingly popular. Towards this, we propose a framework for the case of four parties with at most one active corruption called Tetrad. Tetrad works ov

Dynamic Access Control in a Hierarchy with Constant Key Derivation Cost

Autor: B. R. Purushothama, Nishat Koti

Publikováno v: Advances in Intelligent Systems and Computing ISBN: 9789811033759

While providing access control in a hierarchical access structure, a partially ordered set of security classes can be used to depict an access hierarchy. Data accessible to descendants of a particular security class should also be accessible to the u
