Identity-Based Encryption (IBE) allows the use of an identity as a public key. For example, to encrypt a message one would only need to know the recipient’s identity, the string 'bob@yahoo.com', without needing access to a traditional public key infrastructure. In this program, Brent Waters presents a new form of IBE that uses human biometrics as identities (public keys), discussing the motivations for biometric-based IBE, the primary challenges in developing such as system, and a cryptographic solution called, Fuzzy Identity-Based Encryption.
