Re: Security & Encryption
Hi Blaine, a very nice comment, as usual. According to me you're right when you say that many factors can play a role in the final choise of integration.

I want to add that this can apply also to the success of the integration, it depends on many factors that , many times, are non-technical factors.

Re: Security & Encryption
Some reasons the customers want SoC are lower cost, easier system design, less board space, etc. Many of these are accomplished by SiP as well, but to lesser degree. The step after that is a module, which also offers benefits but higher cost and more parts, including connectors. Typically the decisions are largely based on demand volume and price pressure. However there are myriad factors involved in the final choice of integration.

Re: Security & Encryption
That's correct , it often happens. Well I think that if the only way to realize a particular application is a SiP instead of a SoC , this solution is good because , talking of reasonable cost factors, loosing a customer would be for sure more expensive.

Re: Security & Encryption
We often see people taking about SoC and their design, and one which hear quite often is if it is not feasible to construct a SoC for a particular application, an alternative is SiP, what do you think including cost factors..

Re: Security & Encryption
Hi Blaine,

you're welcome, this blog owns to the same category of the blog that you posted here on the Integration Nation.

As concerns the security standards I report here the description on STMicroelectronics site of this product:
  • Cryptographic engine supporting AES 128/192/256 with multiple modes hardware support

The engine is a dedicated one and the company is working on a further enhancement of the security of the standards utilized as your convinction.

Security & Encryption
Hi Paolo--thanks for all the great details of these integrated designs.  I noted that the PRIME definition suggests 128-bit AES as the approach and has a suggested key management scheme.  In the SoC you are describing here can you comment on what security standards are conded into the security subsystem?  I think in the near future it is possible that 128-bit AES could be replaced by even more secure standards as the computing power catches up to this scheme.

Smart electronics systems, whether worn on our wrist to help maintain a healthy lifestyle, used in our homes to adjust heating and cooling, or built into our car to assist driving, have already shown their ability to improve the quality of our lives.
Electronics systems designed with a smart approach can effectively improve our life by means of some features that can be included in the objects that we use every day inside our houses, offices, studies, cars and so on
This aspect of smart brain technology is the basic idea of a couple of very interesting new smart systems, for car parking and bike sharing respectively
