Abstract: Techniques related to a technique comprising dividing an update into a number of portions, generating, for the first portion, a first portion hash value, generating, for the second portion, a second portion hash value, generating a first branch hash value comprising a hash of a concatenation of the first portion hash value and the second portion hash value, generating a root hash value by concatenating the first branch hash value and a second branch hash value, generating a signature based on the root hash value and a private key, generating an update header comprising the signature, the root hash value, and a hash tree comprising first and second portion hash values, the first branch hash value, and the root hash value, transmitting the update header to a client device for authentication, and transmitting one or more of the number of portions to the client device.

Abstract: A system includes a multiplexer, an input/output (I/O) pin, a logic circuit, and a control register. The multiplexer has multiple inputs, an output, and a selection input. The logic circuit is coupled between the multiplexer and the I/O pin. The logic circuit has a first input. The control register includes first and second bit fields corresponding to the I/O pin. The first bit field is coupled to the selection input of the multiplexer, and the second bit field is coupled to the first input of the logic circuit.

Abstract: Techniques for updating a client device are provided that include receiving, by a client device, a software update and a certificate associated with the software update, verifying, by the client device, the certificate associated with the software update based on a stored public key of the client device, extracting an update scope value from the certificate, comparing the update scope value against a corresponding attribute of the update, and either applying the software update based on the comparing, or rejecting the software update based on the comparing.
