Agile OTP generation
First Claim
Patent Images
1. A computer implemented method for provisioning an OTP generator, the method comprising:
- selecting one or more variance techniques from a set of variance techniques, wherein the variance technique is given by the function OTP=H(F(SKC, SKPC),InputSet), wherein the InputSet is a set comprising K and Time, wherein H is a Hash;
wherein K is a key, wherein SKC is a Symmetric Key certificate, F is a function for use in a variance technique for OTP generation, and wherein SKPC is a Symmetric Key Policy Certificate;
provisioning the OTP generator with the one or more variance techniques; and
enabling a validator to determine which authentication technique is used by the OTP generator.

Abstract
A method, system, and apparatus for agile generation of one time passcodes (OTPs) in a security environment, the security environment having a token generator comprising a token generator algorithm and a validator, the method comprising generating a OTP at the token generator according to a variance technique; wherein the variance technique is selected from a set of variance techniques, receiving the OTP at a validator, determining, at the validator, the variance technique used by the token generator to generate the OTP, and determining whether to validate the OTP based on the OTP and variance technique.
