Samsung's Galaxy A53 offers 5G and a 120Hz screen for $450
The Galaxy A53 and A33 combine decent specifications with large screens, complicated camera arrays and Samsung’s premium aesthetic. They also combine 5G connectivity with the company's more powerful 5nm Exynos chips, arriving for the first time to its midrange devices.
3G GSM encryption cracked in less than two hours
Looks like all that GSM code-cracking is progressing faster than we thought. Soon after the discovery of the 64-bit A5/1 GSM encryption flaw last month, the geniuses at Israel's Weizmann Institute of Science went ahead and cracked the KASUMI system -- a 128-bit A5/3 algorithm implemented across 3G networks -- in less than two hours. If you must know, the method applied is dubbed 'related-key sandwich attack' where multiple values of known differentials are processed through the first seven rounds of KASUMI, then using resulting quartets that are identified sharing key differences, subkey materials can be obtained in round eight to build up the 128-bit key. Sure, it's hardly snooping-on-the-go at this speed, but worryingly this was only an 'unoptimized implementation... on a single PC.' At the same time, the paper condemns the presumably red-faced GSM Association for moving from MISTY -- a more computationally-expensive but much stronger predecessor algorithm -- to KASUMI. Guess we'll just have to stick with Skype.
BenQ rolls out Joybook A53, forgets to invite Penryn
With all these new Penryn-based lappies hitting the shelves, we can't help but be immediately underwhelmed by the BenQ Joybook A53. Sure, the case is fairly attractive, but still, offering up a Core 2 Duo T7250 with just 512MB of RAM is sort of weak. Granted, we've all ideas this one's being aimed at the budget-minded set, so hopefully they'll be down with the 80 to 200GB 5400RPM hard drive choices, dual-layer DVD writer, 15.4-inch WXGA (1,280 x 800) resolution display, trio of USB 2.0 ports, VGA output, audio in / out and 6-cell battery good for around 2.3-hours of usage. Also of note, you'll find integrated Ethernet / WiFi, a 4-in-1 multicard reader and a 0.3-megapixel webcam for pixelated video chats. Unfortunately, BenQ didn't mention how costly this one would be, but it will be rolling out to Poland, Russia, China, Thailand, and Australia right away, while the rest of the world has to wait just a few more months.[Via Electronista]
