DoNews December 16 news (Liu Wenxuan) At present, the world's mainstream instant messaging applications have end-to-end encryption (E2EE) capabilities, and even voice and video calls will provide such privacy protection capabilities, Microsoft's enterprise communications product Teams has finally officially provided this capability to all users after a two-month public beta.
At present, the one-to-one call of Microsoft Teams has finally officially joined the end-to-end encryption protection, and this feature will take effect in Teams after the user chooses to turn on the corresponding option.
While end-to-end encryption makes communications more secure, features such as recording, forwarding, expanding to group calls, and instant captions from Microsoft Teams won't be available in this mode.
End-to-end encryption has become an essential protection for many mainstream instant messaging applications, preventing potential eavesdroppers – including telecom operators, Internet service providers, managers of internal networks, etc. – from stealing the content of communications. At present, mainstream instant messaging applications including Telegram, WhatsApp, LINE, Signal and other instant messaging applications have end-to-end encrypted communication functions, and some even take the default state to open end-to-end encryption measures for all one-to-one sessions.
But there are also commercial companies that will introduce "backdoors" into their apps, with Ars Technica citing information disclosed by Edward Snowden in a 2013 article, and Skype, another microsoft-owned messaging app, which, although it claims to use end-to-end encryption under the public communication channel, has a backdoor that allows Microsoft to leak users' information to third parties.
