About this document
Zero-Knowledge Proofs in Cryptography by suman_cy is a document available to read on EtoBox.
This document summarizes a lecture on cryptographic security concepts. It discusses how semantic security may not be enough to prevent attacks on cryptosystems like ElGamal encryption. It also introduces the concepts of malleability, chosen ciphertext attacks (CCA), and zero-knowledge proofs. Specifically, it defines security against adaptive chosen ciphertext attacks (CCA2) and non-adaptive chosen ciphertext attacks (CCA1). It also discusses complexity classes like P, NP, and NP-completeness in the context
