Electronic signatures cover a wide variety of signatures, with numerous identification procedures for the signer. The signature process is secured with an audit trail.

Digital signatures are electronic signatures that comply to specific identification and security characteristics. They include proof of identity with a certificate and assignment of the signature to the document by encryption.

Requirements for electronic signatures in the US cover a wide range and are mainly based on the requirements of the individual industry.
Requirements for electronic signatures in the EU are covered by the eIDAS regulation. It defines advanced and qualified electronic signatures.

Electronic signatures in general
The basic requirements for electronic signatures. A signature is legally binding if it is available as electronic version.

Advanced electronic signatures
The signature allows for unique authentication of the signer by cryptographically binding the certificate to the document. This can be achieved with certificate based user IDs, using internal PKIs. A software based certificate is sufficient for this kind of signature.

Qualified electronic signatures
The qualified electronic signature needs to be uniquely linked to the signer with a certificate issues by a Trust Center. The certificate is secured on a qualified signature creation device (QSCD), for example a smart card, USB Token or cloud-based hardware security module (HSM). This kind of signature is the legal equivalent to a handwritten signature.

Advanced signatures have a broad range of application, covering EU-wide signing of contracts, country-based biddings and many more. The main advantage for advanced signatures is the use of mobile devices or cloud services for certificates, making the use of advanced signatures easier for everyday life compared to qualified signatures but extensively more secure compared to basic electronic signatures.

SecSign offers advanced electronic signatures with additional hash value calculation and integration in the signature process as compared to just the signature batch for regular advanced signatures. That way, possible changes to the document after signing can be tracked. Additionally, the time stamp provides information on the time and date the document was signed. Compared to regular signature apps on the market the entire process is more secure, by not only providing information about the signer but also about the history of the document.

Certificates are required for both qualified and advanced signatures to explicitly correlate the signer to the signature and the document. It verifies the validity of the signature.

For legally binding qualified signatures information like name, address and others have to be verified officially, for example with a PostIdent procedure. Certificates have to be issued by a Trust Center and secured on a qualified signature creation device (QSCD).

Advanced signatures only require a software-based certificate, issued for example by the in-house PKI server. Data can be verified by the companies own management system to use signatures for in-house processes or collaborating companies. User information can easily be retrieved from the identity management system, for example a LDAP/Active Directory system.

SecSign offers the best PKI for intuitive and secure advanced signatures.

Signatures with a certificate explicitly correlate the signer to the signature and the document. For advanced signatures the certificate has to be secured as a software-version, for example on an internal server. For qualified signatures the certificate has to be issued by a Trust Center and secured on a qualified signature creation device (QSCD).

Certificates can be assigned by previously defined user-IDs (for advanced signatures), smart cards or federally issued IDs (for qualified signatures).

Cryptographically secured signatures (with certificate) provide information about the signer by linking a public key to the signer. The certificate contains information on the name, the electronic signature of the certificate issuer and the corresponding public key. Non-cryptographically secured signatures only fulfill the requirements for general electronic signatures and are not legally binding.
The cryptographically secured signature is secured with two keys: the private key and the public key. The private key is used to encrypt the document (the signature), the public key is used to verify the signature. The private key stays on the mobile device or the in-house sever, respectively. The access to the key is secured by our strong SecSign ID Two-Factor Authentication.

Neither the sender nor the recipient have to worry about the security process. The signature process is intuitive and fast, the recipient is notified immediately about the validity of the signature.

Signatures can either be integrated in the PDF or saved as an external file from the PDF. More information on the PDF signature can be found here.

Most signature applications on the market secure the certificates, soft keys and private keys with a simple user name password combination. An unsafe process, as regularly proven by attacks to all kinds of providers.

With SecSign the signature release is secured with our advanced PKI cryptography based Two-Factor Authentication. Abuse of the signature by attackers or the obtaining of crucial elements, like the public key, by Brute Force attacks or similar methods is impossible.

Electronic signatures, especially digital signatures, simplify numerous processes from internal to international communications, for example signing of contracts, proposals and countless more. It needs more than a simple password username authentication for them to be not only easy but also secure. SecSign offers simple, legally binding and exceptionally secure signatures for any area of application.

You have three different options to use the mobile signature:
The signature key and the certificate are generated and saved on the mobile device. This allows for offline mobile signatures.
Only the hash value is generated on the mobile device. It is sent to the remote signature server and a PKCS7 file is returned. This file is embedded in the PDF file, generating a PDF/A compliant file with PAdES signature.
You can upload a software certificate in the app to use it for mobile signatures.
You have the choice of a PAdES signature with or without visual signature batch. Signatures are available for all kinds of documents, not restricted to PDF files.
