ABSTRACT:
An improved system and method for FLASH BIOS upgrades which is particularly useful in network hubs. Each hub or node which is equipped with a FLASH memory is also equipped with a validation system, which ensures that a received FLASH upgrade is authorized and uncorrupted. Each set of instructions to be flashed is marked both with a vendor authorization digital signature and also a system administrator authorization digital signature, and BOTH digital signatures must be recognized by the validation system before the FLASH memory will be upgraded. Because digital signatures are used for security purposes, flash upgrades can be performed from any location on the network, and are not limited to an administrative node.
