7、ic key certificate and biometric certificate in order to provide cryptographic secure authentication and secure communication on open network environments. This Recommendation also describes the security requirements in biometric digital key generation and protection. The framework described in this
8、 Recommendation can be applied to the biometric encryption and digital signature.

ITU-T X.1088 (05/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Stan
10、dardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), w
11、hich meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within
12、 ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommenda
13、tion is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “m
14、ust“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation
15、may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of t
16、his Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent da

24、metrics digital key framework (TDK) A framework for biometric digital key generation and protection 1 Scope A general framework of biometric digital key is required in order to provide enhanced cryptographic secure authentication and security on telebiometric system. This Recommendation specifies a
25、framework for biometric digital key generation and protection using biometric template with public key certificate and biometric certificate in order to provide secure authentication process on open network environments. This Recommendation also describes the security requirements in biometric digit
26、al key generation and protection for providing biometric authentication and secure communication. However, this Recommendation does not cover the methodology of biometric digital key generation in detail because many different kinds of mechanisms can be used for generating and deriving biometric dig
27、ital key from biometric template. And it also does not specify the detailed telebiometric system mechanism on biometric digital key generation and protection, as many models or system architecture can be used on biometric digital key on open network. 2 References The following ITU-T Recommendations
