Phaedrus Systems Soapbox

 

When not working Phaedrus Systems and a few selected individuals have been musing on various topics: some arising from Phaedsys conference papers, some from things in the news and others items that are to big to go into the Phaedsys Newsletters. The guilty are using pseudonyms as they are writing for themselves not their employers but are going to be well known to many of you (and their employers)..

Flora McDonaldRefresh my Memory…

By Flora McDonald
September 2018

 

Flora has had some real problems with the planned CoreSight configuration article (postponed till later). However she has revisited something that is often overlooked and almost universally under-rated - JTAG memory access. It sounds a bit boring (read memory, write memory, rinse, repeat) but read this tutorial to uncover some clever things that have been overlaid on top of this.>read on....

Gareth Greenwood September 2016

KilroyIoT – Internet of Things/Its only technology

Who, has been in the security industry since before it became trendy. The last newsletter prompted me to think back and ask myself why we keep making the same security faux pax...... .>read on....

Flora McDonaldDriving fearlessly for the future

By Flora McDonald
July 2018

 

Profanity is an odd thing. My children come out with stuff that would make a docker blush and, yet, it is a rare occasion indeed when I resort to a curse. My parents almost never swore; I think in all my years my Mum has only ever sworn twice and although my Dad did swear a little more (and not the obscenities that even the BBC seem to think is OK) it always reserved for the car. I remember, as a youngster, going on a family outing and my Dad would always make sure he had his toolbox in the boot of the car because “the ruddy thing” would breakdown before we got to our destination and he would have to get out and fix it at the roadside. That’s when Mum would tell us all to block our ears. .>read on....

Flora McDonaldGetting your IoT development under control

By Flora McDonald
June 2018

 

The whole world seems to be going IoT crazy at the moment with Internet connected fridges that tell me if I’ve run out of milk (because I’m too busy updating my status to open the door), Internet connected toasters that let me set how brown my toast is via an app on my smartphone and Internet enabled door bells that tell ne’er-do-wells that I’m not home right now and the nearest police are (according to their Twitter feed) at least 20 minutes away. All of these are making my life more fulfilled whilst..... .>read on....

By Roger Sheperd of Chipless December 2016

 

Chris is a great campaigner against the religion that open source software is inherently better and more secure than closed source. However, at times I he goes too far, and assumes anyone from the open-source community can’t be talking sense. One case is Chris’s recent reaction to Linus Torvalds’ commentss.>read on....

This article discusses the IoT is not static, everything changes. The cloud is virtual and, like real clouds, it can move or evaporate altogether leaving you with nothing.

NSA (again)

What the NSA does not want you to know

Gareth Greenwood December 2015

 

A recent article in ArsTechnica reports that NSA can break 512-bit elliptic curve cryptographic keys to facilitate “man-in-the-middle” attacks on internet communications. Apparently, to initiate key-exchange dialogues, most internet servers use numbers generated from only a limited set of elliptic curves..... > read on...
