Abstract

The present disclosure is directed to methods that provide a secure communication protocol by utilizing one step process of authenticating and encrypting data without having to exchange symmetric keys or needing to renew or re-issue digital identities fundamental to asymmetric encryption methodology.

Claims (20)

1. A method to provide secure communications between two parties, comprising:

a client creating and registering a digitally unclonable function (DUF) device identifier for a client's DUF device and providing the DUF device identifier to an existing authentication system;

selecting an encryption generator;

generating a unique, dynamic hash value from the client's DUF device from dynamic, input data using a DUF protocol;

using the unique, dynamic hash value as a seed value for generating an encryption key;

encrypting sender data using the encryption key;

the client packaging the encrypted sender data plus a clear text version of the DUF device identifier and a client identifier to create a client package and sending the client package to a recipient where the client package is processed by a Q-Server;

the recipient using the Q-Server to generate a Q-Server DUF dynamic hash value;

using the Q-Server generated DUF dynamic hash value as a seed value to generate a decryption key, which is the same as the encryption key; and

the Q-Server using the decryption key and the DUF device identifier to decrypt the encrypted sender data;

wherein the unique, dynamic hash value generated from the dynamic input data is unique to each transaction and the Q-Server generated DUF dynamic hash value is also based on each corresponding transaction in order to generate the decryption key; and

wherein the unique, dynamic hash value and the Q-Server generated DUF dynamic hash value are each generated from input data of each transaction and a client authentication input.

2. The method of claim 1 , wherein the existing authentication system is a username/password system.

3. The method of claim 1 , wherein the input data of each transaction is selected from a group consisting of time, date and location.

4. The method of claim 1 , wherein the client authentication input is selected from a group consisting of a username/password and a personal identification number.

5. The method of claim 1 , wherein the Q-server generates the DUF dynamic hash value using a pre-shared secret and a legacy authentication.

6. The method of claim 5 , wherein the pre-shared secret is a time of day.

7. The method of claim 5 , wherein the legacy authentication is the username/password.

8. The method of claim 1 , further comprising:

the client, when ready to send another message, uses new input data to generate a new encryption seed and repeats the steps of claim 1 to securely send and authenticate another encrypted packet.
