Enterprise-Wide Digitally Signed Document Issuance, Authentication & Management
AT.Sign is an industrial grade highly secure product for the issuance of digitally signed documents, certificates, licenses and forms. AT-Sign revolutionises the issuance, verification and management of digitally signed documents because it does not tie down the user to a particular client device e.g. PC, USB smart card etc. where the certificate is stored. Furthermore it does not rely on the inconvenient use of some special hardware that has to be attached to the client device for the reading and storing of the digital certificates.
AT.Sign is a new approach for integrating digital signature features into various software applications. It is provided in the form of a software library with easy-to-use interfaces through which the target software applications can implement digital signing requirements. It is supported by a highly sophisticated and secure scheme for the management of the digital certificates that are used in the signing actions. Full audit trail of the signing actions are kept as an added degree of security in proving authenticity of the signed documents.
AT.Sign uses a secure CertStore for the storing of users’ Digital Certificates. This secure CertStore can be physically separated from the AT.Sign server and is protected by strong encryption.
The access to the Secure CertStore is protected by encryption keys that are further protected by a One-time Password (OTP) accessing scheme. This is a much stronger scheme compared to the standard protection of static password that is commonly used for digital certificate access.
With the digital certificate centrally and securely stored, software applications can gain access to the certificate indirectly through networks for the performance of various document signing and verification transactions. These software applications are typically protected by OTP-based authentication schemes for stronger security on the access control.
This approach opens up the possibility for the user to indirectly access the digital certificate through authorized applications connected from many forms of online devices. This includes the smart phones and tablet PCs on which the storage of digital certification is either technically impossible or is considered as unsafe to do so even if it could be done.
Moreover, the access to the digital certificate, its use in any of the digital signing and verification actions, as well as certificate installation and invocation events are securely kept in the audit trail maintained by AT.Sign. This feature provides additional level of security in the proof of authenticity of documents signed by the AT.Sign software.
