Abstract
The operations required to verify the origin and the authenticity of a software module for an electronic device can advantageously be divided between a general-purpose computer, hereinafter the host, having the electronic device attached to it, and the electronic device itself. More specifically, memory and processing intensive tasks such as syntax checking are done at the host, while security-critical tasks such as cryptographic verifications are done at the electronic device. The present invention thus provides a method for updating software on an electronic device in a trusted way, wherein verification steps are divided between a host system connected to the electronic device, and the electronic device itself. The present invention thus further provides a storage medium containing a program for a host system, causing this host system to perform verification steps with respect to a software update for an attached electronic device, and to appropriately interact with said electronic device.
