ⓘ Mobile Signature Roaming

In mobile telecommunications technology, the concept of Mobile Signature Roaming means an access point should be able to get a mobile signature from any enduser, even if the AP and the enduser have not contracted a commercial relationship with the same MSSP. Otherwise, an AP would have to build commercial terms with as many MSSPs as possible, and this might be a cost burden.

This means that a mobile signature transaction issued by an application provider should be able to reach the appropriate MSSP, and this should be transparent for the AP.

Mobile signature roaming itself requires commercial agreements between the entities that facilitate it. In this respect, we assume that various entities including MSSPs will join in order to define common commercial terms and rules corresponding to a Mobile Signature Roaming Service. This is the concept of a Mobile Signature Roaming Service.


1. Entities involved

  • Acquiring MSSP AMSSP: this is a MSSP acting as an entry point in the Mesh. We can imagine that a commercial model for a mobile Signature Roaming Service is a Mesh of MSSPs which are fully or partially connected between each others.
  • Verifying Entity VE: an entity that can verify a Mobile Signature. A MSSP may be a Verifying Entity as well;
  • Acquiring Entity AE: an entity performing this role is one of the entry points of the mesh, and handles commercial agreements with APs. The entry point in the mesh may be for instance a MSSP, or an aggregator of Application Providers in the context of a particular communities of interests. Thats the reason why we define this more abstract role. An Acquiring Entity implements the Web Service Interface specified in TS 102 204. One or several mesh members may undertake this role and store relevant attributes in order to facilitate the discovery of the Home MSSP by other Mesh members;
  • Identity Issuer: an entity that is able to make a link between a Mobile Signature and an endusers identity. Within a PKI system, this is typically the certificate authority CA and/or a registration authority RA;
