The ring-BASIS assumption is a computational hardness assumption used in lattice-based cryptography, a field of post-quantum cryptography. It posits that certain mathematical problems related to finding a “short” basis in a specific type of lattice structure (called a “ring” lattice) are computationally difficult to solve. This assumption underpins the security of several proposed cryptographic schemes resistant to attacks from quantum computers. It provides a foundation for future-proof digital security.
Context
In crypto news and discussions about future-proof security, the ring-BASIS assumption is relevant to the development of quantum-resistant cryptographic algorithms that could secure digital assets and blockchain networks against quantum computing threats. Reports may mention this assumption when detailing new cryptographic protocols designed to withstand advanced computational capabilities. Its study is critical for ensuring the long-term integrity and confidentiality of digital information in a post-quantum era.
