A research paper presented at the Usenix security conference last week detailed a new technique for retrieving encryption keys from electronic devices, a method that is much faster than all previously ...

Digital security depends on the difficulty of factoring large numbers. A new proof shows why one method for breaking digital encryption won’t work. My recent story for Quanta explained a newly proved ...

Hardware faults are leaking hundreds of supposedly unbreakable encryption keys on to the internet, researchers have found – and spy agencies may be exploiting the loophole to read secret messages. RSA ...

The cost and time required to break 512-bit RSA encryption keys has plummeted to an all-time low of just $75 and four hours using a recently published recipe that even computing novices can follow.

Some of the world’s best known cryptographers – veterans of the crypto wars of the 1990s – say government access to encryption keys is still a bad idea, but is an issue that will never go away because ...
