IoT network will look to the skies for better coverage

Wide-area wireless networks for connecting Internet of Things devices may go global through a partnership between hot IoT startup Sigfox and aerospace company Airbus.Sigfox builds long-range networks for devices such as sensors that need a wireless connection but are too small and power-constrained for cellular radios. Its networks use unlicensed frequencies and don't go more than a few hundred bits per second, but they cost as little as US$1 per connection, per year.The French company has now joined the Mustang Project, co-founded by Airbus Defence and Space and two R&D partners in France. The project plans to combine Sigfox's terrestrial networks with satellite coverage to achieve global coverage.To read this article in full or to leave a comment, please click here

TrueCrypt audit back on track after silence and uncertainty

An effort to search for cryptographic flaws in TrueCrypt, a popular disk encryption program, will resume even though the software was abandoned by its creators almost a year ago.For years TrueCrypt has been the go-to open-source tool for people looking to encrypt files on their computers, especially since it’s one of the few solutions to allow encrypting the OS volume.In October 2013, cryptography professor Matthew Green and security researcher Kenneth White launched a project to perform a professional security audit of TrueCrypt.
