Cyber expert bares encryption pitfalls

End-to-end encryption secures communication and ensures privacy but can become a safe haven for criminals and terrorists to communicate bypassing the security radar.

A packed audience at Rotary Sadan on Monday listened to a city-bred researcher’s assertions on how the Internet was bringing the world together and at the same time taking it apart.

“The Internet has a set of core values, like an end-to-end principle. When I send some data, it should reach the end destination. I don’t care about the intermediaries, what happens to it en route,” Abhijan Bhattacharyya, a scientist in the network embedded infrastructure research group at Tata Consultancy Services in Calcutta, said.
