How to Explain Modern Security Concepts to your Children

Abstract : At the main cryptography conference CRYPTO in 1989, Quisquater et al. published a paper showing how to explain the complex notion of zero-knowledge proof in a simpler way that children can understand. In the same line of work, we present simple and intuitive explanations of various modern security concepts and technologies, including symmetric encryption, public key encryption, homomorphic encryption, intruder models (CPA, CCA1, CCA2) and security properties (OW, IND, NM). The explanations given in this paper may also serve in demystifying such complex security notions for non-expert adults.
