摘要：As we know the data transmission is the need for today’s world. We cannot imagine our life without multimedia applications and data transmission. As we have seen, there are different attacks over data happening like information theft, hacking, phishing, vishing, smishing, etc. Here it is very important to make sure that transactions over media must be safe that means no attack can occur. Hence security becomes an essential task. The multimedia data includes text, image, and audio and video type data. There are several techniques for making our transaction secure are available. The newest enciphering technique has enhanced the safety of multimedia data from illegal operations. The multimedia enciphering method converts original data to others that are not visualized easily and are named as ciphertext. The process to convert a plain text to ciphered form is named as encryption process, and the inverting process of the encryption process that is transforming ciphertext to the original form is named as decryption process. Its numerous applications like multimedia transmission systems, telemedicine, military communication, and remedial imaging. Here, there are quite a lot of conventional encoding algorithms offered. Mainly three conventional algorithms are widely used. They are International Data Encryption Algorithm shorted as IDEA, RSA, and Advanced Encryption Standard shorted as AES. These algorithms are only applicable for the encryption of text and binary data. There is another method used for encryption in which encryption is performed by using a key. On the other hand, the typical algorithms are incompetent to use them in a direct way in multimedia data and color image encryption because of the high correlation among pixels. This paper analyzes different methods of encryption and decryption.
