All Tekron firmware packages – including releases and patches – contain a digital signature, which is used to protect against tampering of the upgrade file. During the firmware upgrade process, this signature is checked. If the digital signature check fails, then the clock will refuse the firmware and the Configuration Tool will report that the upgrade has failed. Additionally, no notifications (SNMP/Syslog) will be sent by the clock.
