At Rambus, we create cutting-edge semiconductor and IP products, spanning memory and interfaces to security, smart sensors and lighting.
HASH-IP-57 hash accelerators, MD5, SHA-1, SHA-2, SHA-3 accelerators
The HASH-IP-57 (EIP-57) is IP for accelerating the various secure hash integrity algorithms like MD5 (RFC1231), SHA-1 (FIPS-180-2), SHA-2 (FIPS-180-3/4) and SHA-3 (FIPS-202), supporting the NIST MAC mode up to 6.4 Gbps @ 450MHz. Designed for fast integration, low gate count and full transforms, the HASH-IP-57 accelerators provides a reliable and cost-effective embedded IP solution that is easy to integrate into high-speed crypto pipelines.

Library element for platform security and packet engines
How the HASH-IP-57 works
The HASH-IP-57 is a family of the cryptographic library elements in the Rambus hardware IP library (formerly of Inside Secure). For example, the HASH-IP-57 is the hash core embedded in the IPsec packet engines as well as VaultIP hardware root of trust cores providing support for MD5 and SHA Hash-based functions. 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 2 to 84 Gbps depending on the configuration and area. Gate counts ranges from 14K to 49K gates depending on the configuration.
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.
