ZUC-IP-48 3GPP ZUC Accelerators

The ZUC-IP-48 (EIP-48) cipher accelerators implement the specification of the 3GPP Confidentiality and Integrity Algorithms as specified by 3GPP and ETSI. Designed for fast integration, low gate count and full transforms, the ZUC-IP-48 accelerator provides a reliable and cost-effective embedded IP solution that is easy to integrate into high speed SoCs for base stations or other equipment requiring 3GPP support.

3GPP ZUC-48 family of accelerators.

Available in 3 configurations / performance grades.

Targeting Base Station designs.

How the ZUC-IP-48 3GPP ZUC Accelerators work

The ZUC-IP-48 is a family of the cryptographic library elements in the Rambus hardware IP library (formerly of Inside Secure). For example, the ZUC-IP-48 is the cipher core embedded in some PacketEngine-IP-97/196/197 protocol aware security engines. The accelerators include I/O registers, encryption and decryption cores, and the logic for feedback modes and key scheduling.

Sustained performance for any object sizes ranges from 4 to 20 Gbps depending on the configuration, area and frequency. Gate count is 20K to 30K gates depending on the configuration. Supported modes: 128-EEA3 and 128-EIA3

Rambus also offers accelerators for the other 3GPP algorithms.

Anti-Tampering Technologies

The design of chip anti-tamper protection needs to adapt and scale with rising threats. Adversaries range from high school hackers to well-funded state actors. Given the threats, it’s useful to think about anti-tamper countermeasures as a hierarchy of safeguards that parallel the type, effort and expense of attacks. Watch this webinar to learn the eleven kinds of tampering attacks and their required skills and resources, and countermeasures for each of these attacks.

Introduction to Side-Channel Attacks

Side-channel attacks conducted against electronic gear are relatively simple and inexpensive to execute. Such attacks include simple power analysis (SPA) and Differential Power Analysis (DPA). As all physical electronic systems routinely leak information, effective side-channel countermeasures should be implemented at the design stage to ensure protection of sensitive keys and data.
