"In quantum cryptography, a sender uses a cryptographic key encoded in a quantum signal to encrypt a message. According to the laws of quantum mechanics, if someone tried to intercept the key, they would destroy it."

"The folks at Signal are taking one of the four post-quantum cryptography algorithms that have been chosen by the US National Institute of Standards and Technology to withstand attacks by quantum computers, but instead of using it to replace their existing public-key encryption system, they are layering the new algorithm on top of what they already have. "We are augmenting our existing cryptosystems," they say, "such that an attacker must break both systems in order to compute the keys protecting people's communications." And they will be rolling out this augmented system to all users in the next few months."

""Nothing in this bill ensures the security of that data, either. Instead it turns every business providing telecommunications in or to the United Kingdom into an attack vector. The best way to guarantee the safety of user data is for it to not exist. Our national security will be significantly enhanced if we store less data, not more, and increase the use of strong cryptography, rather than reducing it.""

"Jim Baker served as the FBI's general counsel from 2014 until 2017, and he presided over the the FBI's attempt to force Apple to undermine its cryptography under the rubric of investigating the San Bernadino shooters; he has long been a prominent advocate for mass surveillance, but he has had a change of heart: in a long, detailed essay on Lawfare, Baker explains why he believes that governments should not seek to introduce defects into cryptographic systems."
