Kasumi, SNOW, and ZUC 3G Ciphers for Telephony Applications


Athena delivers the 3GPP ciphers Kasumi, SNOW 3G, and ZUC as semiconductor intellectual property (IP) cores. Athena’s Kasumi, SNOW 3G, and ZUC cores for 3G telephony complement Athena’s leading-edge TeraFire® public key (PK) cryptography accelerators. Whether your application demands 3GPP cipher performance or the power savings of a dedicated core, Athena’s 3GPP cores are the ideal solution.

Product Description

Athena’s 3GPP cores all feature dedicated, full-width data input, output, and key input ports for maximum throughput and minimum latency. Standardized input and output handshaking simplifies system integration. All Athena 3GPP cores may be delivered with an optional microprocessor bus interface to simplify SoC integration.
