comment What exactly is a negligible (and non-negligible) function?
Numerically what is negligible nowdays? $2^{-80},2^{-70},?$ And can this be justified with existing computational power?

comment Homomorphic Encryption: how does the equality test on ciphertexts work?
Paillier cryptosystem is also randomized. It is additively homomorphic. EAch time the same message is encrypted in different ciphertexts. However the decryption is deterministic... That's why encryption algorithms are described as randomized processes and decryption as deterministic. The former it's for security while the latter it's for correctness

@pAkY88 Well since you are thinking of not decrypting then it seems that you are looking for a homomorhpic hash-tag like primitive...
