Public-Key Cryptography,ryone and a secret key for decryption which is kept secret by the owner. In this chapter we introduce the concept of public-key cryptography. Then we discuss some of the most important examples of public-key cryptosystems, such as the RSA, ElGamal and Rabin cryptosystems. These all provide encryptio

Bit Security of One-Way Functions,necessarily hide everything about ., even if f is one way. Let b be a bit of .. We call . a secure bit of f if it is as difficult to compute . from . as it is to compute . from .. We prove that the most-significant bit of . is a secure bit of Exp, and that the least-significant bit is a secure bit o

Initiative

One-Way Functions and Pseudorandomness,d bit sequences. A famous example is Shannon’s result. Ciphers with perfect secrecy require randomly chosen key strings that are of the same length as the encrypted message. In Chapter ., we will study the classical Shannon approach to provable security, together with more recent notions of security
