For the last six months I’ve been playing around with the idea to run differential power analysis attacks against ciphers in RFID smartcards. This became the topic of my master thesis, but due to the lack of my analogue expertise, someone else was responsible for the measurement setup which however did not work out. Consequently that part failed and I had to produce something without an adequate measurement setup. Unfortunately, the attainable results were not good enough to launch an actual attack, but sufficient to illustrate the power profile of the targeted cards. Read More...
Latex in combination with Bibtex is the defacto standard for writing and citing scientific documents. One would assume, that citing industrial standards is a standard operation in these environments, but apparently that’s not the case, or at least not trivially to achieve.
My favorite citation style is the natdin one (Author, 2000). The first issue coming up with citing standards in this style is: Who’s the author? It’s not the editors, but typically a committee. Read More...
Today I got screwed, because the raid did not boot up, so I had a look and blkid showed me several partitions with the same UUID. UUID, shouldn’t that be unique? Well I figured I screwed something up using dd while setting up the raid, so I got the (bad, I repeat: bad) idea of changing the partitions’ uuids, which seemed impossible (for good reason!). It turns out, these UUIDs are stored in the md_raid superblock at the end of the partition. Read More...
