Conclusion The present document provides guidance for drafting of ETSI Technical Specifications concerning Interfaces, Security Provisions and Inter
29、operability required for implementation of industry-wide mobile signature services. ETSI 7 ETSI TR 102 203 VI .I .I (2003-05) 1 Scope The present document (“TR“) considers the business and functional requirements for a MOBILE SIGNATURE SERVICE. The present document is intended to guide the drafting
30、of the following ETSI Technical Specifications (TS) concerning interfaces, security provisions and interoperability of mobile signatures service solutions. Technical Specification: TS 102 204 - Mobile Signature Web Service Interfaces Technical Specification: TS 102 206 - Security Requirements for Mo
31、bile Signature Systems Technical Specification: TS 102 207 - Roaming of Mobile Signature Service Transactions Together, the present document and the TSs will allow the design and implementation of interoperable mobile signature service solutions. As such, the present document defines business and fu
32、nctional requirements for mobile signature service solutions that leverage smartcards (including the GSM SIM-CARD) and cryptographic techniques (including asymmetric cryptography used in public key infrastructure - PKI) to facilitate the deployment of electronic signature solutions. The mobile signa
33、ture service is considered suitable for the administration and management of all aspects relating to: Acquiring mobile signature capability. Advising and guiding citizens about the use of mobile signature. Managing citizen identity (including Data protection and individual privacy). Processing of si
34、gnature requests from application providers (and providing responses). Maintaining signature transaction records for the citizen. Managing all aspects of signature lifecycle (e.g. validity, expiry, revocation). Supporting service administration and maintenance activities. In defining the Webservice,
35、 the present document makes reference to interactions between different parties and to the end user experience of a mobile signature service at the mobile device. This is done to illustrate concepts and facilitate definition of business and functional requirements for the Webservice - only. Readers
