y Applications requiring a FIPS 140-2 Level 4 certified, tamper resistant module for storing
cryptographic keys should use the IBM 4764 Cryptographic Coprocessor.
y Cryptographic functions demand a lot of a system CPU, but the performance does scale well when
you add a CPU to your system. If your CPU handles a large number of cryptographic requests,
offloading them to an IBM 4764 Cryptographic Coprocessor might be more beneficial then adding a
new CPU.
