Meaning
Electronic verification methods provide cryptographic proof that a specific piece of data, a document or the state of a hardware device is authentic and has not been altered. Security protocols use digital signatures and hashing algorithms to confirm the origin and integrity of a file or a system configuration. Digital attestation allows a remote party to trust the identity of a sender or the compliance of a device without physical inspection.
This mechanism is fundamental to the security of cloud computing environments and the validation of software updates.
Identity Verification
Certificates link keys to entities. Digital attestation verifies these signatures.
Integrity Check
Hash functions generate a unique string of characters that represents the exact state of the data at the time of signing. If the data changes by even one bit, the digital attestation will fail because the new hash will not match the original. This property ensures that contracts or shipping manifests remain exactly as they were when they were first authorised.
System Trust
Hardware-based roots of trust provide a secure environment for generating and storing the keys used in these transactions. The role of digital attestation extends to the boot process of computers where it verifies that the operating system has not been tampered with by malware. By providing a chain of trust from the hardware up to the application level, it enables secure remote interactions in global finance.
