GRECS: Graph Encryption for Approximate Shortest Distance Queries
CCS '15: Proceedings of the 22nd ACM SIGSAC Conference on Computer and Communications SecurityPages 504–517https://doi.org/10.1145/2810103.2813672We propose graph encryption schemes that efficiently support approximate shortest distance queries on large-scale encrypted graphs. Shortest distance queries are one of the most fundamental graph operations and have a wide range of applications. Using ...
