Abstract:

Based on the Java encryption principle, the paper focuses on the insecurity problem in the transter and storage of network data,and describes the key   generation and preservation Using the JCE technique. After that, the paper proposes a password-based data encryption and decryption method, gives a deta  iled explanation and code implementation of the encryption and decryption process, and provides the final results. The analysis of the results shows tha  t the method can realize the secure delivery of sensitive data under the network environment to some extent.

Key words: JCE, J2EE, encryption, decryption
