    RE: What are the security keys and user certificates used for?

    Certificates are used for authentication. The main purpose of certificates is to ensure that a certain public key really belongs to a certain user (e.g. person, organisation, or server/service). In PKI solutions, the issued certificate is fixed to a specific user identity through certificate enrolment. The certificate enrolment means that, for example, in order to get a government-issued ID chip card, one goes to the police station with a passport and fills in an application. After that a certificate is issued.

    The wireless PKI solution entails anonymous key pairs being pre-installed into the WIM cards together with a corresponding PIN (Personal Identity Number) code. A manufacturer's certificate ensures the authenticity of the keys. In the first instance of secure service usage, the Registration Authority (RA) of the WPKI validates the credentials and then requests the CA (Certificate Authority) to create and provide a certificate, thus binding the anonymous key pair to a specific user identity.

    To acquire a SIM card with the security module, the user certificates and the signing PIN, the user has to contact the SIM card issuer.

    For more detailed information about certification enrolment, see WAP specifications from the WAP Forum's website: www.wapforum.org/what/technical.htm
