Email encryption system based on hybrid AES and ECC

Advanced Encryption Standard (AES) and Elliptic Curve Cryptosystems (ECC) are the two most commonly used symmetric and asymmetric encryption algorithms. The paper analyzes both the AES algorithm and the ECC algorithm. Combining with the characteristics of the AES and ECC, a mixed email encryption system is designed, which can solve the problem such as password system speed and security, which can´t efficiently realize the information, data encryption, signature and identity verification. And the hybrid encryption is applied into the email system to enhance the network security of information transmission.
