Poly-IP-53 (EIP-53) is IP for accelerating the Poly1305 hash-based message authentication algorithm (RFC7539), supporting the NIST MAC mode up to 6.4 Gbps @ 450MHz. Designed for fast integration, low gate count and full transforms, the Poly-IP-53 accelerator provides a reliable and cost-effective embedded IP solution that is easy to integrate into high speed crypto pipelines.
How the POLY-IP-53 works
The Poly-IP-53 is a family of the cryptographic library elements in the Rambus hardware IP library (formerly of Inside Secure). For example, the Poly-IP-53 is the cipher core embedded in the Vault-IP-140 platform security engines providing support for TLS1.3 and HomeKit IoT applications (Poly1305 is also available as software implementation in the VaultIP core). 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 1 to 6.4 Gbps depending on the configuration and area. Gate count is around 50K gates depending on the configuration.
