Trusted Execution Environment BIP-32 SYSTEM AND METHOD FOR STORING AND MANAGING KEYS FOR SIGNING TRANSACTIONS BASED ON A BIP-32 PROTOCOL FROM AN INTERNAL KEY OF A CLUSTER MANAGED IN A TRUSTED EXECUTION ENVIRONMENT

摘要

According to an embodiment of the present invention, a transaction signing method performed in a key storage management system implemented by a computer comprises the steps of: configuring a cluster based on the node; and signing a transaction by generating a private key according to a BIP-32 protocol from an internal key of the cluster among a plurality of keys managed in a trusted execution environment of a node existing in the configured cluster.
