Blockchain HSM: A dedicated Hardware Security Module for the needs of tomorrows business

There are many kinds of HSM. All of them are crypto processors that securely generate, protect and store keys. But many of them are solving only a part of a problem. If the use case is not payment or financial transactions related, the choice will often fall on a general purpose HSM. With many upcoming use cases for Blockchain or Distributed Ledger Technology (DLT), the question often is: how can Blockchain security be kept simple? And how does a Blockchain HSM differ from a general purpose HSM?

Often, news reports are focused on the loss or theft of crypto assets worth millions of dollars. Making blockchain technology often a target to take the blame and being called out as not ripe enough for real use cases or their adoption. However, this is not a problem of the blockchain or distributed ledger technology. It can be avoided.

The weak link: The wallet

The weak link in the digital-currency system is the wallet, which is located on the application level and is used to manage the crypto assets. You can read more on this topic in our blog article on securing blockchain and crypto assets.

Here are the most important challenges to meet:

  • Choosing crypto merchants that can ensure a secured platform for their transactions with crypto currencies
  • Using cold storage – but a secure one, please!
  • Choosing a multi-signature solution for storing your crypto assets

Securosys Blockchain HSM: Protecting the key is critical

As with any crypto-based infrastructure, protecting keys is paramount to ensuring a blockchain system’s security. A successful Blockchain system needs highly reliable methods of interfacing with the strong key protection practices afforded by HSMs, and these HSMs must deliver the scaling and flexibility a decentralized blockchain model needs.

The most important key features at glance:

  • Key / Seed Generation
    • The HSM has a dual True Random Generator TRNG entropy source, and NIST SP800-90 compliant RNG.
    • Key derivation on asymmetric keys including built-in BIP 32
    • Direct secure address generation (hash of the public key), which delivers extra PQC protection in the HSM
  • Side-channel protection
    • Prevents extraction of keys without compromising the storage
  • HW-based tamper response
    • Cannot be compromised by software bugs
  • Segregated functions in hardware and hardware “firewalls”
    • Prevents attack by silicon vendor
    • Mitigates risk from compromised software interacting with business logic
    • Process segregation that reduces risks associated with the communication stack being compromised
  • Cryptographic functions in hardware 
    • side channel protection
    • protection from Spectre / Meltdown kind of attacks
    • Field upgradable FPGA implementation
  • Role model with multi factor authentication
    • Segregation of duties avoids risks with single admin having all information
    • Mitigates risks associated with hacked admin accounts
  • Integrated key access control
  • Device clustering for HA redundancy and performance scalablity with integrated secure backup feature
  • Smart Key Attributes (fine-granular access to individual keys)
    • Integrated multi-signature authentication scheme.
  • Support for various crypto currencies
    • ETH, BTC based, Ripple, IOTA and many more
