The rapid development of internet e-commerce is a new model of business activities; and the spread of electronic government in every organization all that needs to look for signing the documents and reports then verification of this signature in the other side. Digital signature authentication scheme provides secure Communication and reduce transmission costs, because the message is contained in the signature itself and no separate message and signature need be sent again.
This research develops a digital signature scheme to introduce a hard digital signature (double secure signature). This duplicate comes first from applying RSA hashing text, and the second from applying hard knapsack to message recovery elliptic curve cryptography ECC.
The combination provides secret signature against current attacking mechanisms using public key algorithms and in the other side, the sender can send the signing message directly to receiver without Arbitrated Digital Signature.
