Compare 9 Inline Memory Encryption IP from 2 vendors (1 - 9)
  • Fast Inline Cipher Engine, AES-XTS/GCM, SM4-XTS/GCM, DPA
    • One input word per clock without any backpressure
    • Design can switch stream, algorithm, mode, key and/or direction every clock cycle
    • GCM: throughput is solely determined by the data width, data alignment and clock frequency
    • XTS: block processing rate may be limited by the number of configured tweak encryption & CTS cores; a configuration allowing 1 block/clock is available

  • External NAND flash protection, designed to secure stored assets with a local key from PUF
    • PUFenc is designed to protect external flash memory and its stored assets.
    • The IP provides asset encryption, such as a learning model for AI or firmware for the chip with a local key from the PUF.
    • It adds an additional layer of security by avoiding using the global key, which is a shared key among ICs after the chip leaves the manufacturing floor.

  • Embedded Flash Protection with Hardware Root of Trust and Lite Crypto Engine
    • PUFef is designed to protect embedded Flash with a Hardware Root of Trust and a lite crypto engine of RC6.
    • The RC6 provides a comprehensive level of security while also minimizing overall size.
    • Before attempting to hack the crypto engine, attackers would first have to destroy the embedded Flash.
