SIGNCRYPTION SCHEME BASED ON ELLIPTIC CURVE CRYPTOGRAPHY

摘要

The invention provides a method and a system forsigncrypting data based on elliptic curve cryptography. In ahead-end system data is encrypted using a random point R anddigitally signed using the random point R. Only the x-coordinateR x of the random point R and only the signature component S signatureof the signature are added to the data after signcrypting thedata. In a smartcard the signcrypted data is verified using therandom point R and decrypted using the random point R.
