Did someone say adventure

Did someone say adventure?! If you missed it on the blog yesterday, I, Kimberly, am officially a Cast Member once again! It's so wonderful to be back in the Disney family and I can't wait for all of the magic ahead of me! . . . #kimandbri #castmember #disneycastmember #unforgettablecast #magic #magicalmemories #disney #disneyworld #waltdisneyworld #disneylife #disneygram #disneyig #fd101look #disneyblogger #featuremydisney #costume #design #makersgonnamake #disneystyle #fblogger #twinstagram #costuming #magickingdom #disneyday #mickeyears #mickeymouse #mickey #disneykid #stylegram #fashiongram

 Disneyland Paris - Sleep

Disneyland Paris - Sleeping Beauty Castle The dragon on its way to take over the castle. With all the great photos we have of Disney we are going to open a new area on our website, is it something you would like to see? #itallstartedwithwalt #itallstartedwithamouse #waltdisneystudios #walt #waltdisney #waltdisneyparis #disney #disneylandparis #mickeymouse #rollercoasters #rollercoaster #mickey #waltstudio #disneyland #photographer #disneylandphotography #castle #disneycastle #photo #instagram #disneyland25 #disneyillustration #disneylandresort

An extract on #mickey

The keystream generator makes use of two registers R and S (100 bits each). The registers are updated in a non-linear manner using the control variables: INPUT BIT R, INPUT BIT S, CONTROL BIT R, CONTROL BIT S. As referred to earlier, any implementation of the cipher contains flip-flops for the R, S regis- ters and the 4 control variables. Furthermore, there must be 7 flip-flops for the counter register to keep track of the number of rounds in the Preclock stage. The keystream production stage in MICKEY 2.0 is preceded by the three stages:- IV Loading, Key Loading and Preclock. Initially the R, S registers are initialized to the all zero state.

Unlike Trivium, MICKEY 2.0 does not allow direct loading of Key and IV bits on to the state register. As mentioned earlier, initially the R, S registers are initialized to the all zero state. Then a variable length IV and the 80 bit Key is used to update the state by successively executing CLOCK KG routine.

MICKEY 2.0 can be protected by an XOR-CHAIN structure. The attacker has the following advantages: He knows the algorithm of MICKEY 2.0 He can use Initial Vectors of his own choice. The key remains secret. He can SCAN-IN and SCAN-OUT vectors as per his choice. To hide the mapping between the scan cells and the actual variables of a cipher is what drove the previous single-feedback and Double-Feedback XOR-Chain schemes. As this is also falling prey to cryptanalysis, as shown in the previous section, we move towards a further secure architecture, named as random XOR-Chain (rXOR-Chain) structure.

The Flipped-Scan countermeasure technique to protect scan-chains was proposed earlier. This involved placing inverters at random points in the scan-chain. Security stemmed from the fact that an adversary could not guess the number and positions of the inverters. This technique was cryptanalyzed using a RESET attack. It was shown that if all flip-flops in the scan-chain are initially RESET, then the positions of the inverters can be completely determined by the 0 1 and 1 0 transitions in the scanned-out vector. As an alternative, the XOR-CHAIN based countermeasure was proposed. The technique involves placing XOR gates at random points of the chain. Security again stems from the fact that an adversary is unable to guess the number and positions of the XOR gates.
