Abstract In recent years, the issue of preserving the privacy of parties involved
in blockchain transactions has garnered significant attention. To ensure privacy protection for both sides of the transaction, many researchers are using
ring signature technology instead of the original signature technology. However, in practice, identifying the signer of an illegal blockchain transaction
once it has been placed on the chain necessitates a signature technique that
offers conditional anonymity. Some illegals can conduct illegal transactions
and evade the law using ring signatures, which offer perfect anonymity. This
paper firstly constructs a conditionally anonymous linkable ring signature
using the Diffie-Hellman key… More >
