Abstract: | We present the first provably secure ID-based key agreement protocol, inspired by the ID-based encryption scheme of Gentry, in the standard (non-random-oracle) model. We show how this key agreement can be used in either escrowed or escrowless mode. We also give a protocol which enables users of separate private key generators to agree on a shared secret key. All our proposed protocols have comparable performance to all known protocols that are proven secure in the random oracle model. |
