中文名称 WAP 公共密钥构造规范
英文名称 WAP Public Key Infrastructure Specification
发布日期 2001-04-24
适用范围 The Wireless Application Protocol (WAP) is a result of continuous work to define an industry-wide
specification for developing applications that operate over wireless communication networks. The scope for
the WAP Forum is to define a set of specifications to be used by service applications. The wireless market
is growing very quickly, and reaching new customers and services. To enable operators and manufacturers
to meet the challenges in advanced services, differentiation and fast/flexible service creation WAP Forum
defines a set of protocols in transport, security, transaction, session and application layers. For additional
information on the WAP architecture, please refer to “Wireless Application Protocol Architecture
Specification” [WAPARCH].
WAP security functionality includes the Wireless Transport Layer Security [WTLS] and application level
security, accessible using the Wireless Markup Language Script [WMLScript]. The security provided in
WAP can be of various levels. In the simplest case anonymous key exchange is used for creation of an
encrypted channel between server and client; in the next level a server provides a certificate mapping back
to an entity trusted by the client; and finally the client itself may possess a private key and public key
certificate enabling it to identify itself to other entities in the network. This document is concerned with the
infrastructure and procedures required to enable the trust relationships needed for authentication of servers
and clients. The term server used here is not limited to WAP gateways and origin servers but may include
third parties and content/service providers using the WAP protocols.
The general model is adaptable to many certificate types including X509v3, X9.68 (currently in draft) and
the certificate format defined in WTLS. The WTLS certificate has the advantage of being very compact,
easily implemented in code, and easily parsed which may be important for initial implementations of WAP
clients. In addition, to the extent possible, the WAP PKI will work interchangeably with existing X.509v3
certificates in existing Internet applications, in order to leverage the existing Internet PKIs. Any new format
that requires major changes to the installed base of certificate-processing products and CA infrastructure is
unlikely to be easily adopted in a short timeframe.
For this reason the general model for this version is that server certificates will use the WTLS certificate
format whereas client certificates will use X.509 format, but as far as possible will not be sent over the air
nor stored on the client.
