'''ID-based cryptography''' (or '''Identity-Based Encryption (IBE)''' or '''identity-based cryptography''' or '''identity-based encryption''') is a [[key authentication]] system in which the [[public key]] of a user is some unique information about the identity of the user (e.g. a user's email address). The first identity-based cryptosystem was a signature scheme developed by [[Adi Shamir]] in 1984, which allowed users to verify digital signatures using only public information such as the user's identity. Modern schemes include [[Dan Boneh|Boneh]]/[[Matthew K. Franklin|Franklin]]'s [[bilinear pairing|pairing]]-based encryption scheme, and [[Clifford_Cocks|Cocks]]'s encryption scheme based on [[quadratic residue]]s.
