Embodiment 1
[0029] refer to figure 1 As shown, it is a schematic diagram of the steps of a multi-party random number generation method provided by the embodiment of this specification, which is applied to the alliance chain system. The method may include the following steps:
[0030] Step 101: The random number initiator generates the root private key Priv of the random number Root ;
[0031] Step 102: The random number initiator distributes the root private key to the random number participants, so that each random number participant obtains its own additional parameter Param-i and distributed private key Priv-i;
[0032] It should be noted that: where Param-i represents the additional parameter corresponding to the random number participant i (i=1, 2, 3...N) (N is the number of random number participants), and Priv-i represents the random number The distribution of private keys corresponding to participant i (i=1, 2, 3...N) is similar to the following.
[0033] Step 103: The random n...
Embodiment 2
[0056] refer to figure 2 As shown, the schematic diagram of the multi-party random number generation device provided by the embodiment of this specification is applied to the alliance chain system. The device mainly includes:
[0057] Root private key generation unit 201: used for the random number initiator to generate the root private key Priv of random numbers Root ;
[0058] The root private key distribution unit 202: used for the random number initiator to distribute the root private key to the random number participants, so that each random number participant obtains its own additional parameter Param-i and distributed private key Priv-i;
[0059] It should be noted that: where Param-i represents the additional parameter corresponding to the random number participant i (i=1, 2, 3...N) (N is the number of random number participants), and Priv-i represents the random number The distribution of private keys corresponding to participant i (i=1, 2, 3...N) is similar to the...
