Claim One:
1. A method 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 an OTP at the token generator according to a variance technique; wherein the variance technique is selected from a set of variance techniques; where the variance technique is given by the function V=G(InputSet1) and wherein the InputSet1 is a set comprising D; wherein D is a unique value for the token generator; wherein G is a function to determine a variance technique for OTP generation; where the OTP is given by the function OTP=H(F(SKC, SKPC), InputSet2, V); wherein the InputSet2 is a set comprising K and C; wherein H is a Hash; wherein K is a key; wherein C is a unique value for the generation of the OTP at the token generator; SKC is the Symmetric Key certificate, F is a function for use in a variance technique for OTP generation, SKPC is a Symmetric Key Policy Certificate; receiving the OTP at a validator; determining, at the validator, the variance technique from a plurality of possible variance techniques used by the token generator to generate the OTP; and determining whether to validate the OTP based on the OTP and variance technique.
