Q: What is the main characteristic of information-theoretic security?

A: It provides security based solely on information theory principles, guaranteeing protection even against an attacker with unlimited computational resources.

Q: How is information-theoretic security different from other security models?

A: It differs from computational security models that rely on assumptions about computational difficulty, instead guaranteeing security based on fundamental information theory principles.

Q: What is the relationship between information-theoretic security and cryptography?

A: Information-theoretic security is a subset of cryptography, specifically referring to cryptographic systems whose security is guaranteed by information theory rather than computational complexity.
