Needham-Schroeder protocol
The term Needham-Schroeder protocol can refer to one of two communication protocols intended for use over an insecure network, both protocols designed by Roger Needham and Michael Schroeder.[1]
The two protocols are:
- The Needham-Schroeder Symmetric Key Protocol is based on a symmetric encryption algorithm. It forms the basis for the Kerberos protocol. This protocol aims to establish a session key between two parties on a network to protect their communication.
- The Needham-Schroeder Public-Key Protocol, based on public-key cryptography. This is intended to provide mutual authentication between two parties communicating on a network, but in its proposed form it is not secure.
