Certificates

• Tap on Start>Settings, and then tap on the System icon.
• Tap on the Certificates icon.
A public key is transmitted as part of a certificate. The certificates listed in the Certificates tabs ensure that
the submitted public key is, in fact, the public key that belongs to the submitter. The hand-held checks that
the certificate has been digitally signed by a certification authority that the hand-held explicitly trusts.
Your EP10 has certificates already preinstalled in the unit. Personal certificates establish your identity, in-
termediate certificates, as the name suggests, identifies intermediate certification authorities and root cer-
tificates establish the identity of the servers with which you can connect.

Choosing a Certificate

Normally, certificates already configured for your network are chosen automatically by the EP10. If a certif-
icate cannot be chosen automatically, you must choose it from the Certificates list.
• To choose a certificate, tap the desired certificate. Your EP10 will connect automatically.
