Abstract
A method for verifying an ad request includes verifying a signature including the ad request using symmetric or asymmetric keys. Using symmetric keys, after an ad request having a first signature is received, a signature generation algorithm is executed to generate a second signature. If the first signature matches the second signature, then the ad request is determined to be verified. Using asymmetric keys, after an ad request having a signature is received, a signature verification algorithm is executed to determine if the signature matches the ad request. If so, then the ad request is determined to be verified.
