AES

Full Title

Advanced Encryption Standard

Context

AES (Advanced Encryption Standard) has several advantages over 3DES (Triple Data Encryption Standard):

1. **Security**: AES is generally considered more secure than 3DES. It supports larger key sizes (128, 192, and 256 bits) compared to 3DES's effective key size of 112 bits (due to its three passes of DES, which originally used a 56-bit key). This makes AES significantly stronger against brute-force attacks¹(https://www.cdata.com/blog/3des-vs-aes).

2. **Performance**: AES is faster and more efficient in both software and hardware implementations. It requires fewer computational resources, making it suitable for a wider range of devices and applications²(https://www.tutorialspoint.com/difference-between-aes-and-3des).

3. **Flexibility**: AES allows for different key lengths, providing flexibility based on the security needs of the application. In contrast, 3DES has a fixed key length, which limits its adaptability³(https://christophegaron.com/articles/research/comparative-study-des-3des-and-aes-which-encryption-algorithm-reigns-supreme/).

4. **Modern Standards**: AES is the encryption standard recommended by the U.S. government and widely adopted globally, while 3DES is being phased out due to its vulnerabilities and slower performance https://www.tutorialspoint.com/difference-between-aes-and-3des https://christophegaron.com/articles/research/comparative-study-des-3des-and-aes-which-encryption-algorithm-reigns-supreme/).

Overall, AES is the preferred choice for modern encryption needs due to its superior security, efficiency, and flexibility.
