Hi Lucky,

Sorry about the intrusion. My name is Robert and I am representing Enova Technology, the original X-Wall real-time encryption chip maker. I read your message to Declan with interests and would like to take this opportunity to respond to your comment.

Interesting, but I'm confused about the "Real-time 64-bit/ 40-bit DES (Data Encryption Standard) Encryption/ Decryption with throughput of 712Mbit/ sec"

Does anyone know about a stronger version of a similar device?

This looks very similar to the dLock device. http://www.enovatek.com.tw/realtime-hd.htm

Perhaps they are using the same ASIC? If so, the product is pure crap. Based on conversations that I had with the booth staff at the last RSA conference, the dLock employs DES and 3DES in ECB mode. Meaning the ciphertext on disk can be broken with the most trivial of cryptanalysis.

** Enova's Response ** I obviously disagree with your assessment of "the product is pure crap." ECB mode of 3DES may appear a bit weaker than the CBC or others two, it's definitely strong enough to sustain brute-force attack. I am not personally aware the ECB with 3DES has been broken before and would like to request you please shed some lights on the subject.

Look forward to your comments. If you are interested in the ASIC, please refer to our web site http://www.enovatech.comhttp://www.enovatech.com.

Thanks, Robert
