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 Is Post-Quantum Cryptography And What Does It Mean For Us?
A recent NSA update addressed the Suite B cryptographic algorithms approved by NSA for protecting U.S. Government data. If you skip ahead to its table of recommendations you will see that some old friends have disappeared — AES with a 128-bit key and SHA-256 have been quietly dropped. The more startling part is in the […]
The SSL/TLS protocol suite is critical for Internet security. Unfortunately, it’s one of those things that’s nice in theory but messy in practice. Good news — a very promising project is bringing help! We commonly say that we use SSL to secure Internet activity. However, that statement taken literally is very out of date! We […]
