Abstract
Methods for the generation and use of session keys for authentication of a user of a server device are disclosed. The methods use a biological objects of the user to generate responses to challenges. During enrollment, the server device receives a password, hashes it a first number of times, and sends the hash to the user. The user interprets the hash as a set of challenges for the biological object, applies the challenges, and stores the responses. During authentication, the server hashes the password a second number of times, less than the first number, and sends the hash to the user. The user iteratively applies second hash to the biological object, compares the responses to the stored responses, and if there is not a match, hashes the challenges again until there is a match. The number of hashes needed for a match is a session key or subkey.
