Ultra-Compact 3GPP Cipher Core
The ZUC1 core implements ZUC stream cipher in compliance with the 3GPP Confidentiality and Integrity Algorithms 128-EEA3 & 128-EIA3 version 1.6. It produces the keystream that consists of 32-bit blocks using 128-bit key and IV.
Multiple configurations of ZUC1 core are available; the number after dash indicates the throughput in bits per clock, so ZUC1-32 version is 4 times faster than ZUC1-8. Enhanced –E3 version is available that supports both EEA3 and EIA3 confidentiality and integrity algorithms. Compact ZUC1-2-E3 core is very small (12K gates).
The design is fully synchronous and available in both source and netlist form. Test bench includes the ETSI/SAGE test vectors.
