为了证明在注册机构（RA）单独注册的ITU-T X.509证书的所有权，已考虑使用生物识别硬件安全模块来提供高级生物识别认证。ISO/IEC 17922:2017提供了使用BHSM的远程生物特征认证框架
在ISO/IEC 17922:2017的范围内，解决了以下问题:
-在电信网络环境中使用BHSM的远程生物特征认证机制；和
-抽象语法符号1（ASN.1）格式和协议，用于实现ITU？T X.509框架中的机制。

To prove ownership of an ITU-T X.509 certificate registered individually with the registration authority (RA), a biometric hardware security module has been considered to provide a high-level biometric authentication. ISO/IEC 17922:2017 provides a framework for telebiometric authentication using BHSM.
Within the scope of ISO/IEC 17922:2017, the following issues are addressed:
- telebiometric authentication mechanisms using BHSM in telecommunication network environments; and
- abstract syntax notation one (ASN.1) format and protocols for implementing the mechanisms in the ITU？T X.509 framework.
