Indian Army Announces Messaging App SAI with End-to-End Encryption for Texts, Calls

With cyber security measures taking centerstage in recent times, the SAI app will seemingly contribute to promoting secure communications in internal circles of India’s defence forces. End-to-end encryption, as has been widely noted, is a much-needed standard in communication apps to improve the level of security, with apps such as WhatsApp, Telegram, Signal and others offering encrypted communication services to keep sensitive information inside a secure bubble.

With end-to-end encryption, conversations (including voice and video calls) are issued from one person’s end as an encrypted and hashed security code. This code is then relayed directly to the sender, making sure that the information is not decoded in between at the server-end. This ensures that malicious individuals cannot intercept the contents of a chat, thus keeping the information secure.

While hackers and cyber criminals are believed to have techniques to bypass end-to-end encryption by tricking individuals into downloading malware that reads screen content, the end-to-end encryption standard is still believed to be a benchmark standard in a secure communication app, which the SAI app is said to enable.
