Identity based key agreement schemes also allow for "escrow free" identity based cryptography. A notable example of such an escrow free identity based key agreement is the McCullagh-Barreto's "Authenticated Key Agreement without Escrow" found in section 4 of their 2004 paper, "A New Two-Party Identity-Based Authenticated Key Agreement". [7]
Identity-based encryption (IBE), is an important primitive of identity-based cryptography. As such it is a type of public-key encryption 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). This means that a sender who has access to the public parameters of the system can ...
Cocks IBE scheme is an identity based encryption system proposed by Clifford Cocks in 2001. [1] The security of the scheme is based on the hardness of the quadratic residuosity problem . Protocol
The Boneh–Franklin scheme is an identity-based encryption system proposed by Dan Boneh and Matthew K. Franklin in 2001. [1] This article refers to the protocol version called BasicIdent. It is an application of pairings (Weil pairing) over elliptic curves and finite fields.

The earliest forms of Identity-based security was introduced in the 1960s by computer scientist Fernando Corbató. [4] During this time, Corbató invented computer passwords to prevent users from going through other people's files, a problem evident in his Compatible Time-Sharing System (C.T.S.S.), which allowed multiple users access to a computer concurrently. [5]
For key authentication using the traditional symmetric key cryptography, this is the problem of assuring that there is no man-in-the-middle attacker who is trying to read or spoof the communication. There are various algorithms used now-a-days to prevent such attacks.
A key-exchange algorithm based on the scheme is the MIKEY-SAKKE protocol developed by the UK's national intelligence and security agency, GCHQ, and defined in RFC 6509. Sakai-Kasahara, as specified in MIKEY-SAKKE, is the core key-exchange algorithm of the Secure Chorus encrypted Voice over IP standard.
