Security of AES-128 in Front of Brute Force Attack

Rikita Gohil

Abstract


Advanced Encryption Standard (AES) is one of the best known and most widely used block ciphers. It has three versions, i.e., AES-128, AES-192, and AES-256 that vary in their key sizes 128, 192 and 256 bits and in their number of rounds 10, 12, and 14, respectively. Data security has been a major and challenging aspect in the modern era of information technology involving the internet and network applications. It becomes especially serious in the cloud environment because the data is in different places all over the world. The purpose of securing data is that only concerned and authorized users can access it. Advance Encryption Standard (AES), is a cryptographic algorithm that can be used to protect our electronic data. However, security is assured irrespective of the hackers are from the noise. This study describes brute force attack on AES (Advanced Encryption Standard) algorithm for encryption and decryption. This system includes plain text, message and a secret key. After the processing of round function on plaintext block, the 12 bits cipher text block is created. Brute-force attack includes analytical examination of all conceivable key groupings until the accurate key is found and there is only one means to attack when it is not possible to take benefit of other weak attributes in an encryption system.
