Multisignature with double threshold condition in the blockchain and its application to and strong keys generating

Ruslan Skuratovskii and Alexandr Kalenyk

Abstract: Improving the reliability of account protection in the blockchain is one of the most important goals of the entire cryptographic arsenal used in the blockchain and cryptocurrency exchange. We propose a new threshold multisignature scheme with a double boundary condition. Access to funds stored on a multisig wallet is possible only when two or more signatures are provided at the same time.

Category / Keywords: cryptographic protocols / multisignature (t,n) with threshold in blockchain, non-commutative cryptography, CSP and CDH problems; Miller-Moreno p-group, generalization of CDH problem, conjugacy problem, multisignature in blockchain.
