    Abstract: The present invention provides a machine-implementable method for generating a random number across participating network devices within a network. The random number has a specific property in accordance with a testing computation. The generated random number is usable in cryptographic systems. The method comprises the steps of generating an initial share value; performing a testing computation on a candidate value, thereby providing testing backup-share values, the testing computation being related to the specific property and the candidate value being related to the initial share value; in response to the result of the testing computation, providing check values and performing a verification of the correctness of the testing computation by using the provided check values, the initial share value, and the provided testing backup-share values; and in response to the verification, providing a commitment value that being derivable from the initial share value and confirming the validity of the initial share value to the other participating network devices by using the commitment value, the confirmed initial share value forming part of the random number.

    Abstract translation: 本发明提供一种机器可实现的方法，用于在网络内的参与网络设备之间生成随机数。 随机数根据测试计算具有特定属性。 生成的随机数可用于密码系统。 该方法包括产生初始共享值的步骤; 对候选值执行测试计算，从而提供测试备份共享值，测试计算与具体属性相关，候选值与初始共享值相关; 响应于测试计算的结果，通过使用所提供的检查值，初始共享值和所提供的测试备份份额值来提供检查值并执行测试计算的正确性的验证; 并且响应于验证，提供从初始股份价值得出的承诺价值，并通过使用承诺值向其他参与网络设备确认初始股份价值的有效性，确认的初始股份价值构成随机的一部分 数。
