This technology concerns a device and method for preventing cache side-channel attacks in blockchain wallet systems, and a recording medium for performing the method. Specifically, it is a security technology that protects blockchain wallet keys from cache side-channel attacks.
Existing technologies had a security vulnerability where blockchain wallet passwords or private keys could be exposed through cache side-channel attacks. To address this, this technology proposes a method that manages cache occupancy status and access patterns during wallet execution, and controls transaction processing and private key operations to prevent them from being inferred by external attackers.
As a result, this technology can enhance the protection level of blockchain wallet private keys and improve the security and reliability of digital asset trading services. It has value for use in the finance, insurance, software, IT, and internet sectors.
