Information hiding is a design principle in computer science where the internal implementation details of a software module are concealed from other modules. Only the necessary interface is exposed, reducing interdependencies and improving system robustness. This practice limits external access to sensitive data or complex logic. It is a core concept for building secure and maintainable systems.
Context
Information hiding is crucial for the security and functionality of smart contracts and decentralized applications. In crypto news, discussions about contract security often relate to how well internal states and sensitive functions are protected from unauthorized external access. Poor information hiding can lead to vulnerabilities that attackers exploit. Best practices in smart contract development emphasize careful design to ensure proper data encapsulation and access control.
This research introduces a novel cryptographic primitive enabling private set intersection where one party learns the common elements succinctly, without revealing their own set.
