(check all that apply) O CRC-32 O mod 2256 O SHA 256 O (x) = 2x+3 Question 56 If two plaintexts Pand p2 give the samashash ie. H (2) = (p) which of the following statements is correct? O If for a given pi it is difficult to find another p2 such that the above condition is met, we say that H(.) has Weak collision resistance. O Pi = P2 with absolute certainty. O If it is difficult to find any two plaintexts i.e. Pi and psuch that the above condition is met, we say that H() has Weak Collision Resistance. O P Pa with absolute certainty: Question 57 Which if the following is the best way of expressing the hiding property of a cryptographic Hash function? O If for a given h (a hash output) it is difficult to find an a such that H (a) = O If for a given , it is difficult to find another #2 such that H (21) = H( O If for a given 1 it is difficult to find another a2 such that H (21) # H ( O If for a given h (a hash output) it is difficult to find an z such that H () # h
