what is AES (Advanced Encryption Standard)?

AES (Advanced Encryption Standard)

"AES (Advanced Encryption Standard) is an algorithm used to encrypt data in a more powerful way. It is a highest degree technique for cryptography, which provides more protection than DES algorithm (Data Encryption Standard) technique."

AES (Advanced Encryption Standard) is a successor of DES algorithm, which is basically designed to provide more security as compare to DES technique, because DES was limited to 64-bit encryption which is vulnerable from brute force attack. AES also works on symmetric key encryption technique but ensure more security than DES.

AES was adopted by many government agencies to encrypt data and conversation, AES became the highest degree encryption standard in the market and it also overcome old DES technique. AES makes possible to encrypt data upto 3 levels 128-bit, 192-bit, 256-bit. where 128-bit takes 10 rounds, 128-bit 12 rounds and 256-bit takes 14 rounds to encrypt and decrypt the data. A round involves several processing steps and mixing of private key to encrypt data.

AES also encrypt block ciphers rather than encrypting one bit at a time. AES provides 128-bit encryption, means that the key length would be 128-bit and 192-bit, 256-bit respectively. The more the key length, more difficult to guess. SO in AES key breaching is not that easy task and brute force not going to break it at all. Although it was found that it is also vulnerable with biclique attack. Apart from security loophole it encrypts data faster than DES, 3DES, which makes it idle for software applications, firmware and hardware use which requires low latency and a high throughput like firewall, router and SSL/TLS protocols all uses AES method to encrypt and decrypt data. DES algorithm method got failed because of its small key length and AES ruled because of its higher key length.
