Needham Schroeder and Millicent

Question

What is this Needham Schroeder and what is this Millicent ?

Answer 1

Needham–Schroeder protocol

The term Needham–Schroeder protocol can refer to one of the two key transport protocols intended for use over an insecure network, both proposed by Roger Needham and Michael Schroeder.^[1] These 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, typically to protect further communication.
• The Needham–Schroeder Public-Key Protocol, based on public-key cryptography. This protocol is intended to provide mutual authentication between two parties communicating on a network, but in its proposed form is insecure.

Millicent 

Millicent is a lightweight and secure protocol for electronic commerce over the Internet. It is designed to support purchases costing less than a cent. It is based on decentralized validation of electronic cash at the vendor's server without any additional communication, expensive encryption, or off-line processing.
