WebIdentity-based encryption (IBE) solves the problem of having to maintain an authenticated PKI. In an IBE: there is a master authority who generates a master public key MPKtogether with a master secret key MSK, and publishes the MPK. To encrypt a message , one needs to know MPK and the identity ID(e.g., the e-mail address) of the recipient.
