New Chaotic Encryption Algorithm and the Application

The technologies of chaotic encryption are widely used in information security fields, such as network communication and image encryption. This paper presents a new chaotic encryption algorithm, which overcomes the limitation of Logistic map, uses tangent function and power function for chaotic function design, and uses chaotic numbers as encryption keys. The new algorithm is perfectly emanative, real-time and security. An example of logistics management and anti-counterfeiting system is given.
