GSL: A Cryptographic Library for the strong RSA Graph Signature Scheme
This work provides a tool for enhancing privacy in infrastructure management, but it is incremental as it implements an existing graph signature scheme.
The authors tackled the lack of privacy-preserving methods in cloud and network infrastructures by designing and implementing GSL, a cryptographic library in Java that enables certification and zero-knowledge proof of graph topologies without disclosing their structure.
Current cloud and network infrastructures do not employ privacy-preserving methods to protect their assets. Anonymous credential schemes are a cryptographic building block that enables the certification of data structures and prove properties over their representations without disclosing the innards of their data structures in zero-knowledge. The GRaph Signature (GRS) scheme enables the certification and proof methods to sign infrastructure topologies represented as graph data structures and use zero-knowledge to prove properties over their certificates. As such, they represent a powerful privacy-preserving method that proves properties over a signed topology graph to another party without disclosing the blueprint of its topology. In this paper, we report our efforts in designing, implementing and benchmarking a Graph Signature Library (GSL). GSL is a cryptographic library realized in Java that implements the graph signature scheme.
