WalnutDSA Signature Verification IP Core for Intel MAX 10

Block Diagram

Solution Type: Qsys Component

End Market: Automotive, Industrial, Medical, Military, Wireline

Evaluation Method: Source Code

Technology: Basic Functions: Miscellaneous

MAX Series: Intel® MAX® 10


A digital signature verification function that is implemented partially in Nios II software and partially in FPGA programmable logic. The function is used for secure boot and secure firmware updates, and may also be used to validate signatures made over messages and certificates. For evaluation purposes, SecureRF provides a terminal-based signing application for Linux or Windows to enable customers to generate WalnutDSA signatures. The user specifies a message file (the file that is being signed), the private key of the trusted signing party, and the output file that the signature will be stored in. For production, SecureRF offers HSM-based key generation and signing appliances to Walnut customers.


  • •\tPerforms signature verification in under 5ms
  • •\tAlgorithm is resistant to all known Quantum Computing attacks
  • •\tVery little ROM, RAM, and logic utilization required
