The use of digital signatures is not new in Indonesia; however, it became much more widespread during the pandemic, which forced more activities to be done online. Many companies and agencies see digital signatures as a solution for validating documents without people having to meet face to face.
Digital signatures can be used for any form of electronic document. They also contain information that can be used to verify and authenticate someone’s identity. But how does they work? Check out the discussion below.
How Digital Sigantures Work
A digital signature is a legitimate signature technology because it has legal force. This is how digital signatures work.
-
The Electronic Certification Operator (PSrE) issues a digital certificate with a unique key pair related to the legal subject (private key and public key). The public key is known to anyone, while the private key is only known to the owner of the signature. Both have unique characteristics, where information or an electronic document is encrypted by one key and can only be decrypted by the partner key.
-
The digital signature has been certified using asymmetric cryptographic methods with a public key infrastructure. The public key is listed in a digital certificate that is general in nature as proof of the identity of the signatory.
-
The public key is attached to the electronic document that has been encrypted with the signatory’s private key. If there is a change in the electronic document, the electronic document reader system will automatically detect and provide a notification. Thus, the identity of the signatory and the integrity of the document can be confirmed.
Important Functions of Digital Certificates
A digital signature that is accompanied by a digital certificate from the digital-certificate issuing institution certifying its validity gives it the same status as an authentic deed. Here is the explanation.
Understanding Digital Certificates
The digital certificate contained in the digital signature is a way of proving the validity of a document or electronic transaction. It proves that the electronic information is correct. Digital certificates make it hard for anyone to modify documents without trace, or forge digital identities.
Important Attributes of Digital Certificates
With digital certificates, digital signatures have five important attributes:
1. Verified Identity
2. Verification
Identity verification using accurate biometrics also ensures that a digital signature on a document or electronic transaction has one important aspect, namely non-repudiation, or undeniability.
3. Authenticity
A digitally signed electronic document is considered authentic when the digital certificate has encryption capabilities and a hash function that prevents modification of the document. When you make modifications to electronic documents, you must re-sign digitally.
4. Validation
Electronic documents require a system to be read and opened. For example, Acrobat Reader is capable of reading portable digital file format documents.
The electronic-document reader application system must be able to detect digital certificates embedded in documents. That way, the digital signature can be recognized and prove that the document is valid according to the digital certificate issued by the PSrE.
5. Time Note
Time records prove when the digital signature was issued and serve as additional information to prove that the electronic document is valid.
