The Exact Security of Digital Signatures- How to Sign with

It is called a hash oracle and it is accessed via oracle queries: an algorithm can write a stxirig z and get back h(z) in time 12) SECURITY OF SIGNATURE

The general method, under control of the key, enciphers a message M to obtain the enciphered form of the message, called the ciphertext C Everyone can use the same general method; the security of a given procedure will rest on the security of the key Revealing an encryption algorithm then means revealing the key
