Keeping track of the provenance and trustworthiness of all of these can be an extremely difficult problem. Any of them might be compromised in a "supply chain" attack to compromise the integrity of a finished product.

In this way, for example, the attacker may hope to gain access to a well defended defence contractor though one of its less secure suppliers.") | |||

For example, unless carefully designed, observing how the power consumed by a processor while encrypting data can leak informaion, ultimately leading to discovery of the encryption key.") | |||

| N 09:56 | Glossary:Speculative execution diffhist +426 Philip talk contribs (Created page with "High performance CPUs use multiple logic blocks in order to perform as much work as possible in parallel. So for example, if a CPU is required to process a list of ten items it might start to "speculatively execute" the processing of an 11th before it has been able to determine that it has completed the list. Even though this wasted effort has to be discarded, a net performance improvement can be achieved.") | ||||

It should be used sparingly and with caution as it can cause offence, also bearing in mind that the real source of the problem might often be shortcomings in the usability of the system or opaque documentation.") | |||
