Line 17:
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|access controls]], [[Rate_limiting|throttling]], [[Audit_trail|audit logging]] and or other security measures.
