Hiding the Data Using Hybrid of LSB and AES in Encrypted Image


  • Purushottam Das





In this technique, which is known as "Reserving Room before Encryption," we first allotted some space for data embedding. Then, the picture was encrypted using the private key, which helps to safeguard the encryption process. Using a different private key, the data is then securely hidden in an encrypted image. Following points, we receive two private keys from the transmitter side, which increased the encryption and decryption processes' security. The data hiding the encrypted image and the two private keys are now sent to the receiver. Receivers can only retrieve data and images if they have access to the encryption key and the data concealing private key, respectively. Thus, the image and data were not easily recovered by the hackers.  Because of this, despite the AES algorithm's mathematical soundness, the primary underlying issues with it, like as speed and the use of subpar or tiny prime integers that have resulted in severe security breaches, may be resolved. A basic and commonly utilised technology worldwide is public key cryptography. The majority of public key algorithms, including AES, are based on modular arithmetic. As a result, performing public key encryption and decryption requires performing several modular multiplications on very large values. As a result, symmetric key algorithms are known to be faster than public key algorithms. It has recently become increasingly commonplace to use GPUs for general-purpose computing. The extremely parallel features have been used to significantly improve the performance of many computer problems.
