Agile OTP generation
First Claim
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 OTP=H(F(SKC, SKPC), InputSet) and wherein the InputSet 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 a 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.
