You need to secure home and office automation hardware, too

My wife really doesn’t like wires. She wants her phone wirelessly charged, she uses Wi-Fi for networking, and is looking forward to controlling our whole house wirelessly. I’m a bit skeptical of the latter as there are multiple standards and I’d hate to invest in something that turned out to be the Betamax of home […]

Encryption, Back Doors, Apple and the FBI

Earlier this week I started to write a post on the conflict between the NSA, FBI, DNA and others regarding encryption and what users should be allowed to do. It’s pretty complicated as there are multiple players. Then came the story yesterday and today about Apple and iPhone decoding. If you haven’t caught it yet, […]

Cryptography Developments: Elliptic Curves, Part 2

Last week I started telling you about an recent interesting paper, “A Riddle Wrapped in an Enigma” by two highly respected cryptographers, Neal Koblitz and Alfred Menezes. I gave you the background last week: the NSA’s long interest in ECC (or Elliptic Curve Cryptography), some reports of NSA back doors inserted into standardized algorithms, and […]

Cryptography Developments: Elliptic Curves

I recently wrote about the NSA’s surprising announcement in August. They urged the community to work on post-quantum cryptography. More surprisingly, they also recommended that organizations that have not yet converted from traditional RSA-based public-key systems to the newer ECC (or Elliptic Curve Cryptography) should not bother doing so. RSA security relies on the difficulty […]

What Are Traffic Analysis and Metadata?

In Learning Tree’s System and Network Security Introduction we discuss “traffic analysis,” noting that even if data are encrypted, one can still find out information by looking at who is sending encrypted data to whom. Along that same line, there has been a lot of discussion in the press recently about “metadata” – information about […]
