128-NIA3

ZUC Integrity Protection Algorithm

Integrity algorithm generating 32-bit Message Authentication Codes using ZUC stream cipher.

Technical Explanation

128-NIA3 uses the ZUC algorithm to generate a 32-bit authentication tag for control and user plane packets. It is widely implemented across Asian 5G networks as part of the ZUC commercial cryptographic suite.

Key Functions

  • Generates 32-bit authentication tag using ZUC keystream generator
  • Deploys widely across China and Asian telecommunication infrastructures
  • Standardized for NAS, RRC, and User Plane integrity protection
