More concepts to explore
Digital signatures
A private signing key and public verification key authenticate messages under security assumptions.
Groups
A group has an associative operation, an identity and an inverse for every element.
Symmetric encryption
A shared secret key supports encryption and decryption under a specified scheme.
Zero-knowledge proofs
A proof can establish a statement without revealing extra witness information in a formal security model.
Chinese remainder theorem
Pairwise coprime moduli give a unique combined congruence class modulo their product.
