A self-extracted secure e-mail software

Abstract

In this project, various public key and secret key cryptographic methods are used to encrypt confidential message and attachments. By using the proposed chaotic cryptography, the encryption/decryption can be done faster. Besides, the cipher text file generated during encryption is small in size so that communication can achieve faster transmission. To further enhance the security, the private key of the chaotic cryptography is encrypted by the elliptic curve cryptosystem (ECC) and digital signature is used in the system. Finally, the cipher text and other key information are packed into a self-executable to achieve high-level security.
