Date: Wed, 27 Nov 2013 21:58:46 +0100 From: Krisztián Pintér <pinterkr@...il.com> To: discussions@...sword-hashing.net Subject: Re: [PHC] CJK character sets remembering 8 idiograms is identical to remembering 8 words. it is perfectly doable, although most people just does not want to do it. an english word typically has the entropy of around 11-12 bits, which is identical to 2000-4000 idiograms. it is not a surprise, words are words, some languages has a little more, some a little less, but not that much different. typing idiograms requires 2-3 button presses, and that is a great advantage over typing the entire word. but with the caveat that most interfaces help with the options, so you don't have to remember the combinations. this is of course unacceptable with passwords. so i would say, chinese are not at an advantage, even if the system is designed around idiograms. but it points into the direction, which i think is right, of using random words as passwords, and possibly having a system to shorten them to save typing. it is more human than remembering characters.

A short 8-character password in a Western script > could perhaps be more like a pass phrase in Chinese-based script.
