The Defense Information Systems Agency (DISA), which manages the Pentagon’s email systems, says it intends to adopt, by default, STARTTLS, an encryption protocol designed to prevent the interception of email messages in transit. "DISA is actively working an acquisition to upgrade the email gateways that will allow us to take advantage of evolving
Fittingly, while we do know a little about 'what', we actually know little about 'where' (in time) we will get commercially viable quantum computers. The 'what' includes massively increased computational power. The 'when' is thought to be some time within the next 15 to 30 years.
Researchers at Fox‑IT have managed to wirelessly extract secret AES-256 encryption keys from a distance of one metre (3.3 feet) – using €200 (~US$224) worth of parts obtained from a standard electronics store – just by measuring electromagnetic radiation. At that distance sniffing the keys over the air took five minutes, but if an attacker got within 30
Westminster Bridge attacker Khalid Masood sent a WhatsApp message that cannot be accessed because it was encrypted by the popular messaging service, a top British security official said Sunday.
Researchers at the Dutch research institute CWI and Google jointly announce that they have broken the SHA-1 internet security standard in practice.
Hackers can shut down entire networks, tamper with data, lure unwary users into cybertraps, steal and spoof identities, and carry out other devious attacks by leveraging centralized repositories and single points of failure.
