    Abstract: Embodiments include a method and a system for signcrypting data based on elliptic curve cryptography. In a head-end system data is encrypted using a random point R and digitally signed using the random point R. Only the x-coordinate Rx of the random point R and only the signature component ssignature of the signature are added to the data after signcrypting the data. In a smartcard the signcrypted data is verified using the random point R and decrypted using the random point R.

    Abstract translation: 实施例包括用于基于椭圆曲线密码学来加密数据的方法和系统。 在头端系统中,使用随机点R对数据进行加密,并使用随机点R进行数字签名。只有签名的随机点R的x坐标Rx和签名的签名组件签名才能添加到签名后的数据中 数据。 在智能卡中,使用随机点R验证加密数据,并使用随机点R进行解密。
