  • This paper defines a new variation of CDH problem where an adversary interacts with a challenger and proves its security is equivalent to the CDH problem. This new problem is useful in designing a cryptographic protocol. To show the versatility of this problem, we present a new identification scheme. Finally, we show a decisional version of this protocol.
