The Cost of Confidentiality in Cloud Storage

In December 2019, Niklas Carlsson and I had two papers about client-side encryption in cloud storage systems published in IEEE/ACM UCC 2019 and IEEE CloudCom 2019.

The first paper (“The Overhead of Confidentiality and Client-side Encryption in Cloud Storage Systems”) empirically characterizes the overheads associated with using client-side encryption and was one of three papers nominated for the best paper award at IEEE/ACM UCC 2019. The second paper (“Delta Encoding Overhead Analysis of Cloud Storage Systems using Client-side Encryption”) looks closer at the biggest problem identified in the first paper (i.e., effectively using delta encoding with client-side encryption).

During the christmas holidays 2016/2017 I created a React-based math quiz with the purpose of learning about React and JavaScript and maybe also refresh my math skills. The source code is available here.

Knekt was developed by a group of students, me included, at Linköping University as our Bachelor’s project during the spring of 2016. Knekt is an interactive web application intended to be used as an aid for teaching historical encryption methods and their weaknesses. If you wish to do some crypto cracking, feel free to try out Knekt. The project’s report can be found here.

I once managed to make a blog using the Django framework. You can check it out here. If you want to make a Django blog yourself, check out Django Girls.
