Advanced Signature
In order to meet eIDAS requirements, YumiSign's advanced signature is based on symmetric cryptography. The user shares a cryptographic key with YumiSign (OpenOTP) when he enrolls his token. This key allows him to confirm the signature requests (transactions) he receives on his application. The digital signature made in the mobile is added in cryptographic form in the chain of digital data that the mobile sends back to OpenOTP.
Qualified electronic signature
Yumisign set up the environment to choose the qualified signature mode and to sign in to Acrobat Reader directly by connecting your qualified signature device appearing in the list of qualified electronic signature creation devices. The user will need to download the correct drivers so that their qualified device reader will allow them to connect their signing device to Acrobat and sign directly into acrobat.
When the document is signed, OpenOTP sends it back to YumiSign for signature by the platform. YumiSign then sends the document to the HSM which contains the signing certificate of the RCDevs CA and its YumiSign subCA which will sign the document before sending it back to YumiSign.
