Abstract: The 20th century is known as the Information age. Development of technology led to the storing and communication of information in the digital form. Digital technology provides easy access to the information through internet and other forms of technology. Transmission of information is also become easy using digital technology. The information stored or communicated may be vulnerable to attacks from the adversaries. All the organizations and individuals are facing the threat of the insecurity of the information of data over the internet. Development of communication media and insecure media emphasizes the requirement to secure the data. The method of securing the information so that it is not stolen by the hackers is known as encryption. The development of multimedia technology has increased the images as the carriers of information. The conventional encryption algorithms are not well suited for the image encryption. Image encryption has developed in the past recent years as an important field. In the image encryption, the substitution and transposition techniques are performed on the pixel values of the image based on the key. One of the mechanisms for image encryption is based on chaos theory. Chaos sequence is used as a key for encryption because of its properties. This method of encryption is more secure and robust.
