Hi Kelly! AES is also used by banks and financial institutions to secure online transactions to ensure that sensitive financial information, such as credit card details and bank account numbers, is kept secure and confidential.
I agree with your point about block ciphers being able to go undetected and having a strong resistance to tampering. It’s important to consider the trade-off between security and speed when choosing an encryption method.
The fact that even a small mistake in a block can compromise the entire block is also worth noting, as it highlights the importance of ensuring that the encryption process is error-free to maintain the integrity of the data being encrypted.
