signature is created by a security module when a request for it reaches the device (SIM card) and after introducing the request to the user with a few explanation prompts, the device asks for a secret code that only the correct user should know. Usually, this is in form of a PIN. If the access control secret was entered correctly, the device is approved with access to secret data containing for example RSA private key, which is then used to do the signature or other operations that the request wanted. The PKI system associates the public key counterpart of the secret key held at the secure device with a set of attributes contained in a structure called digital certificate. The choice of the registration procedure details during the definition of the attributes included in this digital certificate can be used to produce different levels of identity assurance. Anything from anonymous but specific to high-standard real-word identity. By doing a signature, the secure device owner can claim that identity. Thus, the mobile signature is a unique feature for: Proving your real-world identity to third parties without face-to-face communications Making a legally-binding commitment by sending a confirmed message to another party Solve security problems of the online world with identity confirmation (an anonymous but specific identity is often equally good as a high-standards identity) Public services Estonian Mobile-ID See . ParsMSS in Iran Pars Mobile Signature Services Project (ParsMSS) has been designed and produced in Iran for the first time since 2011. Pars Mobile Signature Services (ParsMSS) can be provided in two ways: SIM-Based and SIM-less. Registration Authority (RA) connects to this service and issues the electronic certificate in person or remotely. With this service, financial transactions and documents can be signed digitally. Mobile Ink (Finland) Mobile Ink unites high security and user-friendly access to digital services which require strong authentication and authorization. Subscribers can get mobile signature access to m-banking or corporate applications for example. Mobile Ink is a commercial term associated with the mobile signature solution of Sicap building on Kiuru MSSP platform by Methics Oy. The platform allows simultaneous existence of multiple keys and associated identities with distinct registration procedures. This is used for example as a replacement for RSA SecurID dongles with anonymous but specific identity in corporate access applications.
