Public key cryptography wish list (by )

I have opined in the past about how I'd like better support for public key infrastructure in applications and user interfaces, and a few ideas for how to generalise the signature infrastructure a bit, but I've since been accumulating even more things I think should happen to bring the benefits of strong public-key crypto to the masses.

  • I should be able to use a PGP key to sign my HTTP requests, as an HTTP authentication mechanism. For web apps that support it, the option of choosing a PGP key from my private keyring should appear on login boxes.

  • I mentioned before that I'd like to be able to sign blog comments and posts and other content I submit to web apps in text areas; but I feel like re-iterating it, and point out that this could be handled more neatly by having an extra HTML attribute on the <textarea> suggesting that it accepts signed content, thereby causing my browser to send a detached signature in the submission (as if placed in a second text area, whose name is the value of the attribute, but which does not need to actually exist as an HTML element) if I opt to take it up on the offer. That would be better than the hack recommended in my previous post.

  • Seamless support for signing all, or part, of a Web page, using an element wrapping the content which also refers to the signature (as a URI, or including it inline). For cases like where Markdown has been used to process the original entered content to make it into a Web page, the app should offer a link to the original content wrapped in the original signature; the app could have access to its own private key in order to sign the generated HTML as well, but that's orthogonal to the issue of the original author of the content signing it. Indicating to the user that a region of the page is signed needs to be done in a way that the page itself can't fake with CSS and JavaScript! Given the presence of canvas elements, this will presumably mean it has to involve some UI element outside of the rendering area of the web page - eg, in the browser toolbar.

  • Signing should really be the default state for files, messages sent via various means, etc - my user interface should be marking unsigned messages and files in red!

  • Public key management user interfaces should learn from Petnames, in order to provide a nice user interface while making impersonation attacks hard to do.

  • Seamless support for PGP-signed tar files. No need for a detached signature to download (it's in the tar file itself). Basically, I'd like to have tar able to detect a signed file and check the signature and seamlessly unwrap it to feed into the decompressor and then onto the actual tar file reading itself. This would be particularly pleasing, but in general I'd still argue for every app that reads a file to silently accept PGP-signed files without needing to explicitly unwrap them!

Needless to say, I am mulling infrastructure in ARGON to make public-key infrastructure an integral part of CARBON, and I'd suggest a Petname-based user interface for the management of entity IDs and CARBON global names!

Mars Curiosity and *the* Space Book for Kids (by )

I spent last week working at the Times Cheltenham Science Festival and as part of it I got to go and see a few of the talks which was brilliant. The first one I selected was Mars Curiosity as I spotted it had my old personal tutor Sanjeev Gupta in it. I also got a ticket for Jeany even though at 7 I thought she might be a bit young but she would never have forgiven me if I had gone to see such a talk with out her!

Jean in her Question everything tee

Sanjeev taught one of my favourite subjects at uni Earth Surface Processes so I was very excited to see how Mars research was going especially after seeing the prototype with Jeany earlier in the week. He looked basically the same but has grey hair! He still moves around far too much for a decent photo but that is what energises his talks (of course he didn't recognise me when I said hello - boo hiss but it has been ten years).

The other talker was Lewis Dartnell who was very engaging and handled the childrens' questions brilliantly at the end including the sad, 'When is it coming home?' Jean has been going on about forever vacations on Mars ever since!

Jean did get a bit confused about the fact the robot is ingesting Mars and yet needed batteries! I explained in whispers that it was eating the rock to see what it was made off and not as food. I was impressed she knew what ingesting ment to be honest. They went through the grissly details of man missions and radiation sickness and stuff Jean is still determined to go to Mars if she can or failing that she asked me if she could build a robot to go and then worked out that the 2030 mission would be a good one for her (she'll be 24).

After the talk I had to head over for a meeting but took Jean to Alaric and Mum and Dad to get the book she wanted signed. My meeting ended really quickly and just as well as I received a phone call from Al saying they couldn't find the book! I asked and was told it had sold out but then I saw a copy on the signing table and ended up talking to a lady who turned out to be the authors wife! It was the last copy!

Jean went and got it signed and I felt an ache of sadness for my impact lithologies and endolithic organisms and a moment of doubt about science communication instead of trying to go back but I missed that boat a long time ago. Jean was instantly obsessed by the book and Alaric and Lewis had a conversation involving lots of hands about space ship design. We had to drag the still reading Jean away from the table so that he could go home!

Jean has had her noise in the book ever since, it is a good childrens' book, informative, fun and easy to read but also it is gamified - the kids get to choose where they go on a stella holiday - Jean has always loved books like You Choose so this is right up her street. The illustrations are lovely and colourful, some simple and some intricate giving it a wide appeal to kids as it has different levels you can appreciate it on. It is one of the best I have seen recently and Jean took it into show and tell at school this week along with her cave man stickers and her t-shirt saying Question Everything. She proudly showed the other kids that it was signed with her name in as well 🙂

Jeany was very excited that they had mentioned Liecester as we had spent the previous week going around the space centre there etc... with my friend Becca 🙂 (still need to process the photos and blog about all of that!)

Here is me and Jeany in our festival t-shirts - I'm hiding it at the end as it isn't that flattering of me! hee hee!

Going Back to School (by )

I have been applying for and organising stuff so that I can go back and study - this morning I got a congratulations email from UWE so it looks like I am going 🙂 It is a Post Graduate Certificate in Practical Science Communication. The course itself I have been looking at for the last few years but wasn't really in a position to attempt it - I am nervous about my pervious attempt to go back but feel it is different this time. For a start it is not me going back it is me moving forward and combining the skill sets I have into one area - Science Communication.

I have craft, art, writing, stage skills and so on not too mention a certain degree in geology, I am desperate to show the world the wonder of science and after a week working at the science festival I am even more convinced that the world needs science communicators. The general public are still frightened of many aspects of science, child are still being told they are not the right gender/class/religion to become a scientist. Scientist who have spent their entire time in accademia often fail to realise that they are not portraying information in an easily accessible way even when they are trying to do out reach which doesn't help with it seeming a scary thing.

I am aware that scientists and academics in general tend to get annoyed with what they see as the masses being encouraged to think that science isn't hard that every body can do it - but that is the point a lot of people could do it if they had been caught early enough and in fact I know many people who have retrained into science later in life. People need to see that science is accessible but to become a 'scientist' takes hard work. Also there is still alot of 'science is boring' going around not too mention the confusion over memorising 'facts' and what what science actually is. It is still regarded by many as a dead subject with no room for thinking and innovation - those within science know that this couldn't be further from the truth which is one of the reasons I think this sort of work is important.

I loved doing Science Show Off last year and that raised another communication issue - scientists tend to be specialists these days but really they do need to have some idea of what is going on in different fields - something one day maybe relavent to what they are trying to work out. Not really sure I want to go down the government and policy route to be honest - I want to do public facing, activities for kids, stuff in museums etc... maybe even more festivals though they would have to get behind the general craft and writing workshops/performances I do.

The course should help me with the science journalism I've been wanting to do and just so much more.

The course is part time and done in intense blocks which works much better for me - so I am hopeful.

Excited/Scared 🙂

The Cheltenham Science Festival Highlights (by )

The Science festival was amazing - I just picked out the photos here that aren't going into their own write up about a specific event etc.... It was crazy and mad and informative and showed me just how valuable science communication is!

Science Fun Day at the Cheltenham Science Festival

There was the normal fun circus stuff - lovingly science themed 🙂

I say there is some science over there!

This rather elegant dude reminds me of someone? 😉

Stilt Walking Scientist at the Cheltenham Science Festival

Mary loved exploring.

I know which way to go mummy!

Ok so mainly it was running off but excited running off.

Mary running off to explore the Cheltenham Science Festival

She did grudgingly come back when I started counting.

What do you mean I shouldn't run off on my own at a science festival

I found a random hospital trolly outside one of the venues!

I found a BBC dude with random props wondering around a little lost so I photographed him and then found him the place he needed to be 🙂

The BBC exploder at the Cheltenham Science Festival

I found a ferret!

Ferret!

I don't think it was with the festival but was someone walking their pet - it was funny because one of the suggestions Al had given me for getting more people to fill in the highly important research questionaire was that I should find a ferret!

Guy with fire hydrant Cheltenham Science Festival

Unfortunately I just missed him filling the bag with stuff from the hydrant can - but oooo random stuff at a festival - really?

Aliens on the town hall Cheltenham Science festival

Once more aliens seemed to have taken up residence on the roof of the town hall!

Watching explosions at the Cheltenham Science Festival

Thursday the kids came and joined me after school - they all loved the explosions bit run by the BBC.

Mary over awed by the Cheltenham Science Festival

When we first arrived Mary was over awed and just kept saying WOW! and Ooooo 🙂

Jean finding just how easy it is to over compensate and crash

Jean and her friends found the racing car simulator 🙂

Vroom vroom at the Cheltenham Science Festival

She rather liked it even if she did keep crashing!

Dad found an old sports car with gears and things inside it 🙂

Ferfer looking at the old chain and cog car

See cogs!

gubbings!

It was rather a nice car

They were all just so excited 🙂 Mum found knitting and Al and Andy found robots - it was brilliant 🙂

Excited to be at the Cheltenham Science festival

Science, Knitting and Dr Who! (by )

Yesterday was amazing, I came up with a solution to Matt Smiths retirement from Dr Who - it was simple really Alaric's cubs think he is an incarnation of the Dr anyway! I think we should petition the BBC 😉

Alaric for the next Dr Who!

Then I turned up as a last minute recruit to the Cheltenham Science Festival - I'm doing impact research - basically walking around with shiny tech asking questions for Warick University. The team are lovely - if anyone is about - come over and say hello!

The Impact Research Team at Cheltenham Science Festival

Then I met a lady from Surrey University who is using knitting to explain chemistry - similar to my knitted molecules she is crowd sourcing knitting to create a giant models of minerals 🙂

Knitted minerals

She is giving out the patterns 🙂 And I am going to be knitting up all my blue wool for the project! I am also hoping to catch the lovely Lizzy Burns who's molecular jewellery and glass ware I had on display in March for Science and Engineering week 🙂

Then to cap it all I found a welcome to UWE email in my in box - it is still stuff about processing applications but it made my day 🙂

For the knit wits out there it is The Perovskite Project and they are looking for more knitters 🙂
