IMPROVED BIG DATA SECURITY IN CLOUD INFRASTRUCTURE USING AUTHENTICATION BASED ENCRYPTION MODEL
Abstract
With rapid increase in accumulation of data sources, the security over big data storage is a challenging task. Various issues arise with big data security that includes data privacy, data integrity, and security over infrastructure. Various cryptographic algorithms are developed to secure the big data in cloud, however most algorithm often poses leakage of data. In this paper, a novel solution is developed using secured authentication of bigdata in cloud. It involves authentication of input data in the cloud and security of data using an encryption algorithm in the form of blocks. The validation is conducted on various performance metrics over different attacks to check the efficacy of authentication based security. The simulation results show that the proposed model achieves higher security level than other state-of-art models.
