Mozilla Unveils Firefox Send, a Free Encrypted Filesharing Tool’Side-Channel’ Cyber Attacks Rare, But Chilling Stay on target Let us know what you like about Geek by taking our survey. Skype is finally implementing end-to-end encryption with new Private Conversations.Using Open Whisper Systems’ Signal Protocol, the feature lets users conduct audio calls and send text messages or files without fear of prying eyes.“We know extra protection is important as you share sensitive information over Skype,” Microsoft engineer Ellen Kilbourne wrote in a recent announcement.Exclusive to Skype Insiders, Private Conversations can only be between you and one other contact; this is not yet supported in groups. To initiate a chat, tap the + icon, select ‘New Private Conversation,’ and choose a recipient. Your invitation is valid for seven days; once accepted, all calls and messages moving forward are encrypted (look for the lock icon).Private Conversations are tethered to the device on which they originate. If you’d like to move the discussion to another gadget, you must resend the invitation and start from scratch.With additional security comes additional regulations: Users cannot edit a message or forward a file; only emoticons, files, and audio messages are available to send from the chat window.Once you’ve finished organizing a friend’s surprise party or sharing state secrets, delete (and recover) a Private Conversation. Or, take more extreme measures by ending a consultation; to restart, you’ll need to send a new invitation.“Up next, we’d like to improve the UX around the invite to join a private conversation and bring the experience to the [Universal Windows Platform] client,” Kilbourne said.The content of these discussions will be hidden in the chat list, as well as in notifications, to ensure the secrecy of any information you share.End-to-end encryption (E2EE) aims to prevent potential eavesdroppers—telecom, Internet, or app providers—from accessing cryptographic keys needed to decrypt the conversation.Microsoft joins a growing list of companies, including WhatsApp, Google, and Facebook, that have integrated the open-source Signal Protocol into their messaging platforms.“We’re going to continue our efforts to advance state of the art for frictionless private communication,” Signal’s Joshua Lund wrote in a blog post.“Skype is one of the most popular applications in the world, and we’re excited that Private Conversations … will allow more users to take advantage of Signal Protocol’s strong encryption properties for secure communication,” he added.
