Abstract: The present invention relates to a certificate handling method and system for ensuring secure identification of multiple electronic devices and especially to a method and a system for autonomously creating, transferring, verifying, issuing and status checking (e.g. revocation status) of digital certificates for electronic communication. The present invention provides a certificate handling method, wherein the electronic devices can mutually authenticate each others identity without the use of a certificate authority and the identities of a first electronic device and a second electronic device are mutually authenticated using a personal area network to establish a trust relationship between the first electronic device and the second electronic device.
