Research on Encryption Technology in "Internet +" Big Data Security

In the context of the "Internet +" paradigm and the prevalence of big data, the issue of security pertaining to Internet information is becoming conspicuous. Conventional data analysis technology exhibits limited diagnostic efficiency and inadequate security performance, rendering it unsuitable for meeting the fundamental requirements of information security in the present era of big data. In considering the previous issues, by analyzing encryption technologies such as Twofish, Blowfish, and RSA, this study proposes a hybrid data encryption method by combining RSA and Blowfish algorithms, and a corresponding cloud computing environment based sensitive data sharing policy for efficiency-first scenarios. Experimental data demonstrates that the encryption efficiency and security performance of this hybrid encryption method exceed the baseline algorithm, and can ensure the encryption efficiency and security performance of data-sharing in cloud environment.
