Abstract: Disclosed are an extension cryptographic operation processing system and method. An extension cryptographic operation processing method of a processing device including a trusted execution environment can be performed by at least one processor constituting the trusted execution environment of the processing device.

Abstract: A transaction signature method performed in a system for storing and managing keys, which is implemented as a computer, may include the steps of configuring a cluster based on a node and generating a private key according to a BIP-32 protocol from an internal key of the cluster among a plurality of managed keys in a trusted execution environment (TEE) of the node within the configured cluster and signing transactions.
