Abstract
Method for providing user authentication and a memory for storing a computer program for providing user authentication are described. The method includes the steps of providing a first argument including a one-way cryptographic transformation of a password and a second argument including a one-way cryptographic transformation of a cryptographic combination of the password and a first nonce, computing a first term using the first argument and computing a second term using the first nonce, and comparing the second term with the second argument. The memory storing a computer program, the computer program including, means for providing a first argument including a one-way cryptographic transformation of a password and a second argument including a one-way cryptographic transformation of a cryptographic combination of the password and a first nonce, means for computing a first term using the first argument and computing a second term using the first nonce, and means for comparing the second term with the second argument.
