Detailed Description
Digital Signature
What is a digital signature?
A digital signature is a cryptographic mechanism that provides a secure and verifiable way to sign electronic documents and transactions.
How do digital signatures ensure document integrity?
Digital signatures use hashing algorithms to create a unique hash of the document, which is encrypted with the signer's private key. Any alteration of the document can be detected by comparing hashes.
What legal frameworks support digital signatures?
In the U.S., the ESIGN Act and UETA recognize digital signatures as legally binding, while in the EU, the eIDAS Regulation establishes their legal framework.
What are some advantages of using digital signatures?
Digital signatures enhance security, streamline the signing process, reduce costs, and facilitate easier tracking and auditing of documents.
What challenges do digital signatures face?
Challenges include the need for robust identity verification, reliance on technology, potential legal ambiguities in some jurisdictions, and risks of software bugs or cyberattacks.
