A Novel Elasticsearch Encryption Scheme for Intelligent Transportation System Applications

Elasticsearch is a popular open-source search engine widely used storing, indexing, retrieving and analysing transportation data for intelligent transportation system applications. As the insufficient data protection mechanisms, the information systems and services applying Elasticsearch take greater risk of data breaching. While cryptographic techniques are widely used as an efficient method for ensuring data security, the implementation on Elasticsearch poses a significant challenge. We present a novel Elasticsearch encryption scheme for intelligent transportation system applications and propose some implementation techniques to eliminate or alleviate side effects introduces data encryption. We have implemented a prototype of our proposed scheme to assess feasibility and effectiveness. The experimental results indicate that the scheme is feasible and effective.
