    • An apparatus for calculating a result of a scalar multiplication of a reference number with a reference point on an elliptic curve includes a random number generator and processor. The random number generator generates a random bit. The processor calculates the result of the scalar multiplication based on a calculation algorithm using a first auxiliary variable storing a first interim result representing an integer multiple of the reference point or a coordinate of an integer multiple of the reference point and a second auxiliary variable storing a second interim result representing another integer multiple of the reference point or a coordinate of another integer multiple of the reference point. The processor swaps a value stored by the first auxiliary variable and a value stored by the second auxiliary variable during calculation of the result of the scalar multiplication, if a swap condition depending on the generated random bit is fulfilled.
    • 用于计算参考数与椭圆曲线上的参考点的标量乘积的结果的装置包括随机数发生器和处理器。 随机数生成器生成一个随机位。 处理器基于使用存储表示参考点的整数倍的第一中间结果或参考点的整数倍的坐标的第一辅助变量和存储参考点的整数倍的坐标的第一辅助变量来计算标量乘法的结果 表示参考点的另一整数倍的第二临时结果或参考点的另一整数倍的坐标。 如果满足取决于所生成的随机位的交换条件,则处理器在计算标量乘法的结果期间交换由第一辅助变量存储的值和由第二辅助变量存储的值。

    • The disclosure relates to a system and method for franking mail. An exemplary method for franking mail comprises generating a printing master copy of a postage indicium, encrypting the printing master copy of the postage indicium, transmitting the printing master copy to an operating unit, together with a request that, after the postage indicium has been printed out, information about the printing of the postage indicium is to be stored, decrypting the printing master copy in a secure area of the operating unit in order to print the postage indicium, whereby the secure area is a component of a universal standard program for displaying and/or printing text and/or graphic elements, and responsive to a request for printing the postage indicium, storing information about the printing in the printing master copy and/or in an authorization database, whereby the printing of the postage indicium is blocked if the information about the printing is already present.
    • 本公开涉及一种用于邮寄邮件的系统和方法。 用于邮寄邮件的示例性方法包括生成邮资标签的打印主副本,加密邮资标签的打印主副本,将打印主副本发送到操作单元,以及在邮资已经被打印之后的请求 要存储关于打印邮戳的信息,将操作单元的安全区域中的打印主副本解密,以打印邮资标签,由此安全区域是用于显示的通用标准程序的组件 和/或打印文本和/或图形元素,并且响应于打印邮资标签的请求,将关于打印的信息存储在打印主副本中和/或在授权数据库中,从而如果打印邮资标记被阻止,则 有关打印的信息已经存在。
