The core systems of this bank handle tens of millions of transactions per day on average. The traditional RSA encryption system faces the threat of quantum computing decryption, requiring an early PQC migration while ensuring the security of data transmission between the "two locations, three centers" disaster recovery sites.
Deployed PQC hardware-accelerated HSMs to complete the PQC algorithm migration of the core systems.
Deployed quantum security gateways to achieve quantum-secure communication between the "two locations, three centers" sites.
Upgraded the quantum key management system to enable unified management of quantum keys and traditional keys.
Equipped more than 50,000 teller terminals with quantum-secure USB shields.
Achieved a smooth PQC migration of the core systems without affecting normal business operations.
Ensured the security and reliability of data transmission between the "two locations, three centers" sites.
The transaction processing capacity of the system increased by 20%, meeting the needs of business growth.
Became a benchmark case for PQC migration in the Chinese banking industry and took part in developing quantum security standards for the banking sector.
