Signature Protocol Definition and Examples

Understanding Signature Protocol for e-Signing

Navigating the world of electronic signatures can be daunting without a clear understanding of key concepts like the Signature Protocol. At its core, a Signature Protocol refers to the rules and processes governing the way electronic signatures are created, validated, and authenticated when documents are signed digitally.

What is a Signature Protocol?

A Signature Protocol encompasses the technical and procedural methods used to secure an eSignature. It ensures that the signed document's origin and integrity are verifiable, protecting against tampering and fraud. These protocols often involve cryptographic techniques to bind the signature to both the signer and the document, making sure that any alterations are easily detectable.

Examples of Signature Protocols

1. Public Key Infrastructure (PKI):

   • Definition: This is a framework used to create, manage, distribute, use, store, and revoke digital certificates. PKI involves a pair of keys (public and private) where the signer uses their private key to create a unique digital signature, and anyone with access to the public key can verify the signer’s identity.
   • Example: When signing a contract using GoodSign, a user’s digital certificate is used to create a PKI-based signature. This certificate can be verified by the recipient to ensure the document’s authenticity.

2. Secure Hash Algorithm (SHA):

   • Definition: A cryptographic hash function that takes an input and produces a fixed-size string of bytes. SHA ensures that any change to the input results in a drastically different hash value, thereby highlighting any alterations.
   • Example: GoodSign might use SHA to generate a unique hash for a document at the time of signing. Any post-signing modifications to the document would change the hash, signaling potential tampering.

3. Advanced Electronic Signatures (AdES):

   • Definition: These are enhanced electronic signatures that meet specific requirements for high security and legal validity. AdES often involves additional identity verification steps and secure key generation.
   • Example: During the signing process on GoodSign, users might undergo multi-factor authentication to produce an AdES, ensuring an extra layer of security and trust.

Why is Signature Protocol Important?

Implementing a robust Signature Protocol is critical for maintaining the integrity, authenticity, and non-repudiation of signed documents. It ensures that electronically signed agreements are legally binding and secure, reducing the risk of disputes and fraud.
