Strength of Hardware Cryptography

Cryptographic algorithms can be implemented in both software and specialized hardware. A hardware solution is often desirable because it provides these advantages:
  • More secure protection to maintain the secrecy of keys
  • Greater transaction rates
If a data security threat comes from an external source, a software implementation of the cryptographic algorithm might be sufficient. Unfortunately, however, much fraud originates with individuals within the organization (insiders). As a result, specialized cryptographic hardware can be required to protect against both insider and outsider data security threats. Well-designed hardware can:
  • Ensure the security of cryptographic keys
  • Ensure the integrity of the cryptographic processes
  • Limit the key-management activities to a well-defined and carefully controllable set of services
