SM4 Compliance Test (GB T 32907-2016) - 1M Iterations
🛡️ SM4 Algorithm Compliance Test (GB/T 32907-2016)
======================================================
[OVERVIEW]
This workflow performs a strict compliance verification for the SM4 Block Cipher Algorithm, adhering to the Chinese National Standard GB/T 32907-2016 (Information security technology—SM4 block cipher algorithm).
It specifically implements the "Example 2" (Appendix A.2) validation scenario, which requires 1,000,000 iterations of encryption to verify the algorithm's stability and correctness.
------------------------------------------------------
⚙️ TECHNICAL SPECIFICATIONS
• Algorithm: SM4 (GM/T 0002-2012 / GB/T 32907-2016)
• Mode: ECB (Electronic Codebook)
• Padding: NoPadding
• Iterations: 1,000,000 (Feedback Mode: Output C_i becomes Input P_i+1)
• Implementation: Java Snippet (High-performance loop)
------------------------------------------------------
📚 DEPENDENCIES & CREDITS
This component is powered by the industry-standard cryptographic library bundled within KNIME:
• Library: Bouncy Castle Crypto APIs (bcprov)
• Provider: org.bouncycastle.jce.provider.BouncyCastleProvider
• Note: No external JAR installation is required. This workflow runs on any standard KNIME Analytics Platform.
------------------------------------------------------
🧪 VALIDATION VECTORS (Appendix A.2)
To pass the compliance test, the output of the 1,000,000th iteration must match the standard exactly.
