What is PKI (Public Key Infrastructure)?

Public Key Infrastructure (PKI) technology proven as the only technology available today that ensures non-forgeable signatures.

In a PKI system, each user has two keys: a public key and a private key. These keys can be used for encrypting and decrypting information, for digitally signing electronic information and for verifying the authenticity of their owner.

While the public key is distributed widely, the corresponding private key is held by its owner in a secure place. While both keys are mathematically related, the public key cannot reveal the private key. This makes PKI a great technology for Digital Signatures.

The EU Directive 1999/93/EC for Digital Signatures recognised and defined a stronger type of electronic signature, the Advanced Electronic Signature. Only Public Key Infrastructure (PKI) digital signatures meet the requirements for such signatures. Advanced digital signatures provide not only stronger user authentication, but also protect the integrity of the data signed, thus ensuring non-repudiation of the transaction by the signer.

What is the Difference between Digital Signatures and Electronic Signatures?


Digital signatures and electronic signatures are both used to authenticate documents and ensure their integrity, but they differ in terms of the underlying technology and level of security they provide.

Digital Signature is the highest form of signature and content integrity as well as universal acceptance. Digital signatures are based on Public Key Infrastructure (PKI) and are a result of a cryptographic operation that guarantees signer authenticity, data integrity and non-repudiation of signed documents.

A digital signature cannot be copied, tampered or altered. In addition, because they are based on standard PKI technology, signatures made within one application (e.g. Microsoft Word, Adobe PDF) can be validated by others using the same applications.

On the other hand, an electronic signature is a proprietary format (there is no standard for electronic signatures) that is an electronic data, such as a digitised image of a handwritten signature, a symbol, voiceprint, etc. that identifies the author of an electronic message. Electronic signatures are vulnerable to copying and tampering, making forgery easy. In many cases, will require proprietary software to validate the signature.

What is a Digital Signature?

Digital signatures (standard electronic signatures) take the concept of traditional paper-based signing and turn it into an electronic “fingerprint.” This “fingerprint,” or coded message, is unique to both the document and the signer and binds both of them together.

Digital signature ensures the authenticity of the signer. Any changes made to the document after it is signed – invalidates the signature, thereby protecting against signature forgery and information tampering.

Digital signatures sustain signer authenticity, accountability, data integrity and non-repudiation of documents and transactions.

What is an Electronic Signature?

Electronic signatures are defined as an electronic sound (e.g., audio files of a person’s voice), symbol (e.g., a graphic representation of a person in JPEG file), or process (e.g., a procedure that conveys assent), attached to or logically associated with a record, and executed or adopted by a person with the intent to sign the record.

An electronic signature is easy to implement, since something as simple as a typed name can serve as one. Consequently, electronic signatures are very problematic with regards to maintaining integrity and security, as there is nothing to prevent one individual from typing another individual’s name. Due to this reality, electronic signatures that do not incorporate additional measures of security are considered an insecure way of signing documentation.

What kinds of documents should I sign?

Documents sent regularly using Secured Signing service include contracts, non-disclosure agreements (NDA), proposal acceptances, change orders, Ad proofs, expense reports, purchase orders, rental/ lease agreements, independent contractor agreements, time sheets, and many more.
