Dr Kamakoti's solution for WhatsApp traceability without breaking encryption is erroneous and not feasible

Author: Anand Venkatanarayanan - Published 2019-08-14 10:19

...the claim that WhatsApp encryption can remain unchanged and adding originator information without breaking encryption into the message is possible is unsupported by the protocol design.

The proposal by Prof. Kamakoti also contains other elementary errors. It assumes that encryption and decryption of messages are done only via public key cryptography which was invented in 1976. But as the discussion above illustrates the signal protocol used by WhatsApp is much more modern, uses a combination of symmetric and public key cryptography and also the double ratchet which continuously discards encryption keys after single use.
