I'm taking up a cryptography class and this is for an assignment. We're asked to find the differences between AES/RSA in the different modes of operation vs the one timepad method.
From wiki, I can see that in all the different modes of operation(Eg CBC), the ek(encryption) is done. However, not much is said about what kind of encryption is used. What difference will it make if I use AES or DES in the encryption part in the process? I get that RSA is better than DES/AES dues to assymetricity. Apart from this difference, I can't figure out how the using just AES instead of DES would make AES with CBC would make it better than DES with CBC.
So, I read up and found this which says that the main reason why AES is better that DES is because of the key size. Is this the only difference?
