A system and method for the generation of cryptographic keys for authentication and secure communications. The invention is an improvement over other existing authentication and encryption methods because it is not susceptible to hackers who have access to previous login sessions since authentication data is unique to each session, it is not susceptible to hackers using brute force attacks to determine underlying algorithms due to the complexity of the method and the extensive ability to customize the underlying data, and it allows for a key length as large as the message and unique to each login session which is what Claude Shannon showed to achieve the so-called perfect secrecy. The disclosed invention is also an improvement over existing authentication and encryption methods because it allows for multiple valid responses in each login session.
