Embodiment Construction
[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0047] Refer to attached figure 1 , further describe in detail the concrete steps to realize the present invention:
[0048] Step 1. Generate the public and private key pair of the group owner.
[0049]The group owner uses the elliptic curve key generation formula in the blockchain asset system to generate his own public key and private key pair.
[0050] The formula for generating the elliptic curve key is as follows:
[0051] D=d×G
[0052] Among them, D represents the public key corresponding to the private key, d represents the private key, and the value range of d is [1,n-1], n represents the order of the base point on the elliptic curve, × represents the point product operation on the elliptic curve, G represents the base point on the elliptic curve.
[0053] Step 2, distribute weighted private key components.
[0054] According to the identificat...
