MULTI-FACTOR AUTHENTICATION USING QUANTUM COMMUNICATION
First Claim
1. A user device adapted to perform a method of enrolling a user for multi-factor authentication that uses quantum communication with a computer system that implements a trusted authority, the method comprising, with the user device:
- receiving device factor information associated with the user device;
receiving user factor information associated with the user; and
storing the device factor information and the user factor information in memory of the user device for use in multi-factor authentication with quantum communication.

Abstract
Multi-factor authentication using quantum communication (“QC”) includes stages for enrollment and identification. For example, a user enrolls for multi-factor authentication that uses QC with a trusted authority. The trusted authority transmits device factor information associated with a user device (such as a hash function) and user factor information associated with the user (such as an encrypted version of a user password). The user device receives and stores the device factor information and user factor information. For multi-factor authentication that uses QC, the user device retrieves its stored device factor information and user factor information, then transmits the user factor information to the trusted authority, which also retrieves its stored device factor information. The user device and trusted authority use the device factor information and user factor information (more specifically, information such as a user password that is the basis of the user factor information) in multi-factor authentication that uses QC.
