Abstract

One or more embodiments of the invention provide a method and a device for generating and verifying a linkable ring signature in a block chain. The method may include: determining a signer array (P_j,ID_j), the signer array (P_j, ID_j) comprising a public key P_j of a signer and a unique identifier ID_j of an asset to be spent held by the signer, G being a base point of an elliptic curve, | G | =p and p being a prime number, x_j being a private key of the signer and 0 <x_j<p; generating a key image I according to the private key x_j of the signer and the signer array (P_j, ID_j); and when alinkable ring signature is generated for the transaction M related to the asset to be spent, adding the key mirror image I to the linkable ring signature.

Description

technical field [0001] One or more embodiments of this specification relate to the field of blockchain technology, and in particular to a method and device for generating and verifying a linkable ring signature in a blockchain. Background technique [0002] Blockchain technology (also known as distributed ledger technology) is a decentralized distributed database technology, which has many characteristics such as decentralization, openness and transparency, non-tamperable, and trustworthy, and is applicable to many In application scenarios with high demand for data reliability. However, due to the complete openness of blockchain ledgers, information privacy cannot be guaranteed. Contents of the invention [0003] In view of this, one or more embodiments of this specification provide a method and device for generating and verifying a linkable ring signature in a blockchain. [0004] In order to achieve the above purpose, one or more embodiments of this specification provi...
