Poly-IP-53 (EIP-53) is IP for accelerating the Poly1305 hash-based message authentication algorithm (RFC7539), supporting the NIST MAC mode up to 6.4Gbps @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.
Poly1305 family of accelerators
Available in several configurations / performance grades
Supporting TLS1.3 IoT HomeKit
The Poly-IP-53 is a family of the cryptographic library elements in Inside Secure’s HW IP library. 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 SW implementation in Vault-IP-140). 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 1Gbps to 6.4Gbps depending on the configuration and area. Gate count is around 50K gates depending on the configuration.
Inside Secure also offers the required ChaCha20 cipher to match the Poly1305 algorithm to match the HomeKit.
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.
