Webddh is a secure PRF in the random oracle model assuming the Decision Di e-Hellman assumption holds in G. This PRF is clearly key homomorphic. This is the full version of a paper that appeared in Crypto 2013 [BLM+13]. yStanford University. Email: fdabo,klewi,hartm,[email protected] 1 WebNov 18, 2024 · Examine if the following functions are PRFs: 1.F1(k, x) = F(k, x) ⊕ x 2.F2(k, x) = F(F(k, 0n), x) 3.F3(k, x) = F(F(k, 0n), x) F(k, x) where denotes concatenation. Attempt: For 1. a standard distinguisher would be: x1 ⊕ x2 = = y1 ⊕ y2, where x1, x2 are two inputs and y1, y2 are their outputs respectively. So F1 is not a PRF. For 2. WebCrypto.
