unique pemutation using 3DES
Hi, I am working on a problem where we have to share account ids with another party. Account ids in this problem are 64 bit numeric quantities. We do not want to reveal the id but want to preserve 1:1 mapping to allow 3rd party to correlate using the transformed id on some event stream. The number of ids is huge... 23 Apr 2010 21:23

entropy and the Yarrow PRNG for key generation
Hi, I'm currently reading the paper about Yarrow (a secure PRNG from Schneier and others, see http://www.schneier.com/paper-yarrow.html), and I'm trying to understand the importance of the amount of entropy that the PRNG provides for its quality as generator for bulk data encryption keys. Although Yarrow may... 23 Apr 2010 17:55

Explicit Encapsulation Within the Ciphertext or Implicit Markup Database.
These are the proposed new broader crypto classes. Explicit Encapsulation. All existing mainstream cryptography belongs in this class in which the plaintext is transformed and encapsulated directly as cipher text and later recovered piecemeal by some special means. The ciphertext string is rather like a zip-f... 20 Apr 2010 16:17

Are online password managers safe to use?
I have been looking into online password managers lately because I think they are much more useful than locally stored password managers such as KeePass. I have four candidates in mind: Passpack.com Lastpass.com clipperz.com Mitto.com Besides interface usability, they all claim to use AES 256 bit ... 23 Apr 2010 21:23

Shamir's Identity Based Encryption -- consensus
Back in 1978 Adi Shamir described something he called Identity Based Encryption (IBE). He stated three characteristics that I paraphrase here: 1. Create a secure communications without (external key exchanges) communications 2. No directories (this excludes certificates) 3. No third parties (I assume he means ... 20 Apr 2010 16:17

Trying to explain A, B and C in Cryptology
Off-topic, but it's too fun to not share... I'm trying to explain who Alice, Bob and Charlie is (you know, basic RSA and PubPriv key encryption) to my wife and daughter. After a really good explanation (I think, of course) - my daughter concludes: "So You're Alice in Wonderland trying to send a message to Bob ... 20 Apr 2010 16:17
