# Digital Signature Verification ⎊ Area ⎊ Resource 3

## What is the Authentication of Digital Signature Verification?

The cryptographic validation ensuring that a transaction or message originates from the claimed private key holder, typically via asymmetric cryptography. This step is foundational for non-custodial trading and the integrity of on-chain derivative instructions. Without robust authentication, the system's security model collapses.

## What is the Integrity of Digital Signature Verification?

The assurance that the signed data, representing an order or cancellation request, has not been altered in transit or storage. Verification confirms that the public key corresponds to the signature applied to the exact message hash. This prevents replay attacks and unauthorized state changes.

## What is the Protocol of Digital Signature Verification?

The established procedure, often involving elliptic curve cryptography, by which a recipient system confirms the validity of a signature against a public key and the associated data payload. Adherence to these cryptographic standards is non-negotiable for trustless financial instruments.
