Multipeer Connectivity As consumer web technologies and enterprises race towards cloud infrastructure, there is a curious and significant counter-movement towards connected devices. In this age of mobile computing, the possibilities of collaboration, whether in work or play, have never been greater.

iMessage Privacy iMessage is probably one of the most trendy instant messaging systems. Apple presents it as very secure, with high cryptographic standards, including end-to-end encryption preventing even Apple from reading the messages. Is this true? Quick answers What we are not saying: Apple reads your iMessages.What we are saying: Apple can read your iMessages if they choose to, or if they are required to do so by a government order. Voluntary - Bitpost Bitpost private decentralized messaging Source Enabling Communications, Anywhere, Anytime: Arduino Yun as a possible Mesh Extender Platform Regular readers of this blog will know that we have been looking at a variety of hardware options for the Serval Mesh Extender. The Serval Mesh Extender is a device that combines ad-hoc WiFi meshing with long-range license-free UHF packet radio to allow the easy formation of mesh networks spanning useful distances. Typically the UHF packet radio has a range about ten times greater than WiFi. This means that in ordinary suburban and urban areas we get a range of a block or two, and in open rural areas the range can be in the kilometres. We run our award winning Serval Mesh software over the top, providing an easy to use communications system that lets you use your cell phone without cellular coverage, for example, during a disaster, or when you and your friends are near one another outside of the range of your native network.
Public-key cryptography An unpredictable (typically large and random) number is used to begin generation of an acceptable pair of keys suitable for use by an asymmetric key algorithm. In an asymmetric key encryption scheme, anyone can encrypt messages using the public key, but only the holder of the paired private key can decrypt. Security depends on the secrecy of the private key. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key. After obtaining an authentic copy of each other's public keys, Alice and Bob can compute a shared secret offline. The shared secret can be used, for instance, as the key for a symmetric cipher.

How my sexual health searches ended up in the hands of the world's biggest tech companies Updated 7 minutes agoFri 23 Nov 2018, 12:22am When I searched through the vast amount of data my phone and laptop shared in a week, there was one thing that really weirded me out: how my health information was being unexpectedly sent to multiple companies. And it wasn't just search engines sharing my health-related web browsing — I even found a Victorian Government website delivering data directly to two of the world's biggest tech companies. And when I asked them about it, they re-wrote large chunks of their privacy policy overnight.
