简介
Data Security nowadays is becoming a primary concern for any communication process especially when it is having confidential information and has to travel through an insecure medium of communication. There are many techniques to protect the data from unauthorized access. Methods such as Symmetric Encryption makes use of a secret key which is used by the sender and the receiver for encrypting and decrypting the contents respectively. Methods such as asymmetric encryption makes use of two different keys to do the same task. The former method is faster as compared to the latter but lacks in terms of security. The latter method makes use of a public key infrastructure to make the encryption process public but decryption private hence increasing the overall complexity. The best known symmetric cipher AES [1] makes use of 256 bit keys to do the encryption. Very wellknown asymmetric method RSA [2] makes use of 1024 bit keys to do the same job, thus increasing the time and space complexity at the cost of increased security. Another asymmetric counterpart ECC [3] makes use of a completely different approach by converting the characters into affine points of an elliptic curve. It makes use of 160 bit keys and produces the same result at a much better pace as compared to RSA. In this paper a novel efficient model of Hybrid Encryption involving AES and ECC is put forward which encrypts any multimedia data ie text, image, audio, video, etc. The advantages of both AES and ECC are utilized to create a more powerful hybrid cipher to bridge the gap of speed and security. With the help of lesser sized keys the time factor required to do the …
