Hardware Security Modules (HSMs) are dedicated systems that physically and logically secure the cryptographic keys that are at the heart of digital signatures.
How HSMs Are Used for Electronic Invoicing:
- Electronic invoices are digitally signed with a secure private signing key, which requires an HSM capable of performing certificate authority management tasks.
- The HSM stores the keys within the secure confines of the appliance throughout the key life cycle.
- The HSM enables the organization to secure digitally certified invoices and to cryptographically bind the identity of the certifying party to the invoice.
By storing cryptographic keys in a centralized, hardened device, HSMs can eliminate the risks associated with having these assets housed on disparate, poorly secured platforms. In addition, this centralization can significantly streamline security administration.
