Zusammenfassung:	The present invention is a system for exchanging new certificate based on current certificate and a method thereof. A certificate exchanging server is established to receive an existing certificate in a certificate-owned device, and this existing certificate is used with the certificate request sent by a device without certificate to obtain a new legal certificate corresponding to the existing certificate from a Certification Authority. The new legal certificate is used for the device without certificate. The present invention solves the problem of limited signing ability of the certificate-owned device by exchanging the certificate. The present invention also provides a computer-readable medium for a method for exchanging new certificate based on current certificate.
