Information is the key source to mankind and securing it is the biggest task. Unauthorized access of information deals with the security. Image security is emerging as a major problem with the exponential growth of data stored and transformed through the network around the world. Many cryptographic techniques are used for securing the data like images, audio and text files. These days, the security of information has become more vital in data transfer through networks and storages so everyone knows the importance of data encryption to maintain the confidentiality and privacy of information transmitted across different networks. Cryptography is linked with the process of converting ordinary plain text into indistinct text and vice versa. Symmetric key algorithms i.e., Advanced Encryption Standard (AES), employs the same key for encryption and decryption and is one of the most secured algorithms. Hence in this work, an efficient VLSI design and implementation of LFSR based hybrid cryptography algorithm is presented. A large key size ensures the randomness, but proportionally maximizes the network load with high complexity. To overcome this problem, the random numbers were generated using a Linear Feedback Shift Register (LFSR) scheme for key function. This algorithm is appropriate for encryption and decryption of online streaming data.
