Remember the Clipper chip? NSA’s botched backdoor-for-Feds from 1993 still influences today’s encryption debates

The Register

More than a quarter century after its introduction, the failed rollout of hardware deliberately backdoored by the NSA is still having an impact on the modern encryption debate.

Known as Clipper, the encryption chipset developed and championed by the US government only lasted a few years, from 1993 to 1996. However, the project remains a cautionary tale for security professionals and some policy-makers. In the latter case, however, the lessons appear to have been forgotten, Matt Blaze, McDevitt Professor of Computer Science and Law at Georgetown University in the US, told the USENIX Enigma security conference today in San Francisco.

In short, Clipper was an effort by the NSA to create a secure encryption system, aimed at telephones and other gear, that could be cracked by investigators if needed. It boiled down to a microchip that contained an 80-bit key burned in during fabrication, with a copy of the key held in escrow for g-men to use with proper clearance. Thus, any data encrypted by the chip could be decrypted as needed by the government. The Diffie-Hellman key exchange algorithm was used to exchange data securely between devices.

Safari’s Intelligent Tracking Protection is misspelled, says Google: It should be Dumb Browser Stalking Enabler

The Register

Google security researchers have published details about the flaws they identified last year in Intelligent Tracking Protection (ITP), a privacy scheme developed by Apple’s WebKit team for the company’s Safari browser.

In December, Apple addressed some of these vulnerabilities (CVE-2019-8835, CVE-2019-8844, and CVE-2019-8846) through software updates, specifically Safari 13.0.4 and iOS 13.3. Those bugs could be exploited to leak browsing and search history and to perform denial of service attacks.
