eIDAS Compliant Qualified Seal​

Electronic seals are the equivalent of electronic signatures for data/documents, but it applies to data/documents generated solely by machines.

A Qualified Electronic Seal is an EU approved tool used for signing documents by large legal entities, such as joint-stock companies, limited-liability companies and public institutions. It is a proof of will based on trust, which guarantees integrity, confidentiality and authenticity of signed documents or data of any kind.

      One could perfectly use this PP for devices that are not managed by a TSP. A device certified against this PP may be used by users that wish to store they signing keys remotely, as it would be the case e.g. for a legal person implementing a QSCD to issue qualified seals. Even if the PP is suitable for cryptographic modules used by QTSP, the PP can be used for devices other than TYPE 2 ones.
