TPM chip support is now available on selected Advantech routers. TPM (Trusted Platform Module) is a tamper-resistant hardware chip placed on the PCBA of the router that can store cryptographic keys and then use those keys to encrypt or sign information while a VPN connection used. Storing your cryptographic private keys on a TPM chip brings additional security level to your communication.
TPM 2.0 chip is now available in standard for ICR-44xx product line and optionally also the ICR-2701, ICR-2734, and ICR-2834.
The TPM 2.0 chip specification:
• Supports both RSA (1024 or 2048) and ECC (P-256 or P-384) ciphers
• Has a flash memory that can store more than 50 RSA or ECC keys
• Is compliant with TCG TPM specifications 2.0
• Is certified at FIPS 140-2 level 2 and Common Criteria (CC) according to TPM 2.0 PP at EAL4+
For a closer description of how to use this additional security feature on the routers see the Commands and Scripts Application Note that lists the most important tpm2 subcommands. For a detailed description of these subcommands, please take a look at the tpm2 manual pages. The tpm2 commands required to set up the TPM keys usable for an IPSec tunnel are provided in the ICR-44xx Configuration Manual.
