"The same Public Key Infrastructure principles that have authenticated websites"

A public key infrastructure (PKI) is the system of digital keys, certificates and trusted procedures that proves who is on the other end of an electronic interaction and encrypts the data they exchange. Think of it as a verified digital mailroom and set of padlocks: one key is shared publicly to lock messages and a matching secret key unlocks them, which helps prevent fraud, supports secure transactions, regulatory compliance and preserves investor trust in a company’s digital operations.

"tamper-resistant environments including Hardware Security Modules (HSMs)"

Hardware security modules are specialized, tamper-resistant devices that store and use encryption keys and perform sensitive cryptographic tasks inside a locked “vault” so the keys never leave the device. For investors, they matter because they reduce the risk of data breaches, help companies meet security rules, and protect the integrity of transactions—factors that can affect a firm’s legal exposure, customer trust, and long-term value.

"Hardware Security Modules (HSMs), Trusted Platform Modules (TPMs)"

Trusted platform modules are small, dedicated chips or components built into devices that store digital keys and perform security checks to prove the device and its software are genuine. For investors, TPMs matter because they reduce the risk of data breaches, fraud and downtime—similar to a locked safe for critical information—which can protect a company’s reputation, lower legal and cleanup costs, and preserve customer trust and long‑term value.
