RC6 is a symmetric-key algorithm which encrypts 128-bit plaintext blocks to 128-bit ciphertext blocks. The encryption process involves four operations: integer addition modulo 2w ,...

The Full-Domain Hash (FDH) signature scheme [3] forms one the most basic usages of random oracles. It works with a family F of trapdoor permutations (TDP), where the signature of m...
