Embodiment Construction

[0040] figure 1 It represents an embodiment of a quantum attack-resistant threshold signature scheme oriented to blockchain cross-chain and asset custody.

[0041] The steps of the embodiment are as follows:

[0042] Step 1. Each node in the blockchain network runs the protocol together (i) Distributed key generation protocol, generates the private key share of each node in the blockchain network and jointly generates the public key. The protocol is implemented by Algorithm 1, and the specific steps of Algorithm 1 are as follows:

[0043] Algorithm 1.F Key-generation :

[0044] (1) Node P I ,(I∈{1,...,n}) (where P I represents the I-th node) set a set △ I ={i∈{1,...,N}|i≡I mod n} (where N represents the length of the input based on parameter w; n represents the number of nodes; p is a prime number, is the capacity parameter);

[0045] (2) Node P I ,(I∈{1,...,n}):

[0046] (a) Generation order is p q finite field of (p is a prime number, q is an integer) on a ce...

Abstract

The invention relates to an anti-quantum attack threshold signature scheme oriented to block chain cross-chain and asset hosting. The scheme comprises two protocols: (i) a distributed key generation protocol and (ii) a distributed threshold signature generation protocol. The scheme is executed by three steps: (1) nodes in the block chain network jointly execute a protocol (i), generate respective private key shares and jointly generate a public key; and (2) for the threshold value t, t nodes in the block chain network are selected to jointly execute a protocol (ii), and the message is signed. And (3) each node in the block chain network takes the message, the signature and the public key as input, calls a standard W-OTS signature verification algorithm to verify the signature and outputs a verification result true / false. The invention can be used in any block chain network, plays a role of digital signature in the network, has important value when being applied to the block chain network, and can be applied to cross-chain transaction and digital asset hosting in the block chain.

Description

technical field [0001] The present invention relates to a digital signature technology, and more specifically, to an anti-quantum attack threshold signature scheme for blockchain cross-chain and asset custody. Background technique [0002] With the advent of Bitcoin, blockchain technology came into being. Digital signature technology is a crucial security-critical technology in the blockchain, which plays a key role in anti-counterfeiting, tamper-proof, and identity confirmation in the blockchain. In order to improve the security of digital signatures in the blockchain, some early blockchains tried to introduce multi-signature technology. However, this technology does not take into account the problems of node downtime, network failure, hardware failure and malicious nodes in the actual blockchain network. Once the above problems occur, the multi-digital signature mechanism cannot work normally in the blockchain. Therefore, the present invention introduces threshold signa...
