Line 14: The function is called an ''Oblivious'' Pseudorandom Function, because the second-party is ''oblivious'' to the function's output. This party learns no new information from participating in the calculation of the result. However, because it is only the second-party that holds the secret, the first-party must involve the second-party to calculate the output of the [[Pseudorandom function family\|pseudorandom function]] (PRF). This requirement enables the second-party to implement [[access control]]s, [[Rate limiting\|throttling]], [[Audit trail\|audit logging]] and or other security measures. == History ==
