Hertzbleed allowed an attacker to recover the private key used by the post-quantum SIKE cryptographic algorithm by measuring the power consumption of the Intel or AMD CPU performing certain operations. Minerva was able to recover the 256-bit secret key of a US-government-approved smart card by measuring timing patterns in a cryptographic process known as scalar multiplication. The recently discovered side channels tracked as Minerva and Hertzbleed came to light in 20, respectively. While the encryption algorithm in the device was sound, the electromagnetic emissions emanating from the device were enough to provide a side channel that leaked the secret key.įurther Reading A new vulnerability in Intel and AMD CPUs lets hackers steal encryption keysSide channels have been a fact of life ever since, with new ones being found regularly. To the surprise of the Bell Labs engineers who designed the terminal, it caused readings from a nearby oscilloscope each time an encrypted letter was entered. Side-channel exploitation made simpleĪs Wired reported in 2008, one of the oldest known side channels was in a top-secret encrypted teletype terminal that the US Army and Navy used during World War II to transmit communications that couldn’t be read by German and Japanese spies. By carefully monitoring characteristics such as power consumption, sound, electromagnetic emissions, or the amount of time it takes for an operation to occur, attackers can assemble enough information to recover secret keys that underpin the security and confidentiality of a cryptographic algorithm. The attacks enable a new way to exploit two previously disclosed side channels, a class of attack that measures physical effects that leak from a device as it performs a cryptographic operation. If I had any lingering doubts as to whether the Husqvarna Battery Series was truly a professional line of tools, this experience has quelled it with enthusiastic finality.Researchers have devised a novel attack that recovers the secret encryption keys stored in smart cards and smartphones by using cameras in iPhones or commercial surveillance systems to video record power LEDs that show when the card reader or smartphone is turned on. The light weight and performance of this saw will leave limbing and small tree cutting jobs with nothing wanting. There’s run time that is available for the pro landscaper to work a full day. Husqvarna got it right with the chainsaw and this system. I almost hate including “36V” in the name because it cuts like a saw with a bigger number on the package. Husqvarna simply gets better performance out of their system than I’ve experienced with anyone else. If there’s one thing that surprised me more than anything else, it was the cutting speed that I got out of the Husqvarna 36V Chainsaw. It’s not just about the voltage and amp hours. I learned a lot about battery systems with the Husqvarna T535i XP. What you’ll have to weigh is that there’s no gas and oil to buy and mix. It’s a larger upfront investment than going with Husqvarna gas-powered options. There’s going to be one obstacle that will get in the way of some people pulling the trigger on this system: cost. I actually used a belt eyelet right next to it with a carabiner to attach the saw to my belt loop as a climbed to where I was taking care of some trimming. There’s a rope attachment on the back that’s handy for pulling the saw up to where you are. It’s lightweight enough to use easily when it comes to trimming duties that require climbing. The T535i XP 12-inch top-handle chainsaw is well suited to limbing and cutting down small diameter trees. Let’s talk more about the Husqvarna 36V Chainsaw now that we’ve shown you that this really is a pro minded battery platform. Husqvarna T535i Top Handle Chainsaw Features This helps when you want to truly ditch the gas can on a particular trailer or load-out. They’ve also given professional landscapers the runtime they need to put in a full day’s work. Husqvarna designed a battery solution that gives homeowners on larger properties what they need to get the job done. I’ve only tested the 26.1 amp hour battery pack so far, and you’re looking at 235 minutes to fully charge it. You use the same charger on all 4 battery options. There are also several points to secure the battery cable to the shoulder or hip straps should you need to keep it out of your way. The backpack snaps across your midsection and chest will ensure a correct fit along with three adjustable heights for the battery to install in the harness.
