Digital signatures are considered one of the key security aspects, next to the data encryption, single sign-on technologies and strong authentication mechanisms, like two-factor authentication, risk-based authentication and dynamic authorizations.
Digital signature ensures that the signatory of a digital document can be identified unambiguously and his or her name is documented together with the signed document, the date, and the time. You can use the digital signature to approve documents or objects in the SAP applications that are set up for its use.
The digital signature is implemented in the SAP system with the help of the component Digital Signatures and Encryption and is based on Secure Store and Forward (SSF) mechanisms (see SSF Administration Tasks) and on public-key technology. You can use digital signatures in SAP systems either together with a security product or without. When you configure digital signatures for SAP solutions without using a security product, your users are prompted to re-authenticate using their AS ABAP passwords.
If you are looking to improve your corporate security, a product, such as SAP Single Sign-On, introduces features that are not directly available with the SAP systems, like for example digital signatures for SAP GUI for Windows, advanced SSO technologies and encryption, strong authentication and risk-based authentication, etc.
You need to consider implementing digital signatures using SAP Single Sign-On when:
