comment how many pairs of plaintext-ciphertext are needed before we break AES?
so does this mean , we cannot infer the key in any reasonable amount of time ?

comment Weakening of Pallier cryptosystem due to ciphertext equivalence and order in CryptDB
Ok this is an interesting reference, my hunch could be wrong too. Lets see if others have any answers. Initially was trying to see if we can deduct the random values $r_1,r_2$ by knowing their ciphertexts are equal but that seems not possible
