IBM hardware supports a broad range of industry-standard encryption algorithms and security standards, implemented directly in silicon and cryptographic modules. These are used across systems like IBM Power Systems and IBM Z.

🔐 1. Symmetric Encryption Standards

These are used for fast data encryption (bulk data, storage, network traffic):

• AES (Advanced Encryption Standard) – primary standard (128, 192, 256-bit)
• DES (Data Encryption Standard) (legacy)
• 3DES / TDES (Triple DES) (legacy but still supported)

👉 These are hardware-accelerated in IBM processors (via CPACF).

🔑 2. Asymmetric Encryption Standards

Used for key exchange, authentication, and digital signatures:

• RSA (Rivest–Shamir–Adleman)
• ECC (Elliptic Curve Cryptography)
  • NIST curves: P-256, P-384, P-521
  • Modern curves: Ed25519, X25519

👉 ECC is widely used in modern secure communications and supported in IBM hardware.

🧾 3. Hashing & Integrity Algorithms

Used for data integrity and digital signatures:

• SHA-1 (legacy)
• SHA-2 family:
  • SHA-224, SHA-256, SHA-384, SHA-512
• SHA-3 family:
  • SHA3-224, SHA3-256, SHA3-384, SHA3-512
  • SHAKE128, SHAKE256

👉 These ensure data hasn’t been altered.

🔐 4. Message Authentication & Security Functions

IBM hardware supports:

• HMAC (Hash-based Message Authentication)
• Digital signatures
• Random number generation (true hardware RNG)

👉 These are critical for secure APIs, banking, and authentication systems.

🛡️ 5. Hardware Security Module (HSM) Standards

IBM cryptographic adapters (Crypto Express, PCIe coprocessors):

• Comply with:
  • FIPS 140-2 / FIPS 140-3 (U.S. government crypto standard)
  • PCI HSM standards (for payment security)

👉 These ensure tamper-proof key storage and processing.

⚛️ 6. Post-Quantum Cryptography (Next-Gen Standards)

IBM is leading in quantum-safe encryption, including:

• ML-KEM (CRYSTALS-Kyber) – key exchange
• ML-DSA (CRYSTALS-Dilithium) – digital signatures
• SPHINCS+ / Falcon (future standards)

👉 Already integrated into newer IBM systems like z16/z17.

🌐 7. Encryption for Data Protection (Use Cases)

IBM hardware supports encryption across all layers:

• Data at rest → Disk/storage encryption
• Data in transit → TLS/SSL acceleration
• Data in use → Secure enclaves / protected memory

👉 This is called pervasive encryption in IBM systems.

🧠 8. Key Management & Protection Standards

• Secure key wrapping (keys never exposed in plain form)
• Hardware-protected keys (inside HSM)
• Support for:
  • PKI (Public Key Infrastructure)
  • Secure key lifecycle management

👉 Keys are often never visible outside hardware.
