摘要
The present invention provides a method for sign-encrypted data based on elliptic curve cryptography and systems. The head-end in the system, the data is encrypted using a random point (R) and is digitally signed using the random point (R). Random point data to the data after the signature encrypted only x- coordinate (R x ) of the (R) and only one signature component (s signature ) of the signature is added . In the smart card, the encrypted signature data is verified using the random point (R), it is decrypted using the random point (R). ; elliptic curve cryptography, the head-end system, a random point, smartcard, a conditional access system.
