Abstract
A method and system of authenticating a user are provided. A request for a resource is received by a server, from a user device. A predefined number is received from the user device. A first number and a second number are created. The first number is sent to the user device. A first discrete logarithm is determined based on a challenge code and the first number and sent to the user device. A first pass code is calculated via a second discrete logarithm based on the first discrete logarithm, the predefined number, and the first number. A second pass code based on the second discrete logarithm, is received from the user device. The first pass code is compared to the second pass code. Upon determining that the first pass code is identical to the second pass code, the user device is allowed access a resource associated with the computing device.
