| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, a lot of incident of password leakage by illegal access occurs frequently, therefore a password list attack is also increasing. As the counter measure, a user should not use same password on multiple services and should change the password periodically. However, many users do not follow the rule because it is difficult to come up with many safe passwords. A password auto-generator and password management tool is known as one of the solution for the problem. Since it is generally hard to enter the auto generated password, a lot of time is required for entering such a password. In this paper, we pay attention to the fact that a word of natural language such as English word is easy to enter for a man who master the language. The proposed novel technique is a method for generating a password which is easy to enter because it is similar to English word. The word that sounds English is generated by using a Markov process. Furthermore, we also pay attention to the fact that a man can memorize temporarily about 5～9 characters which is called a chunk. It is shown that high-speed input is made possible by the password which is constructed by concatenating two or more chunks. By experiment, the password which is generated by the proposed techniques can reduce the input time by 50% compared to a random password which has same entropy. The result of this paper enables us to realize safer and user-friendly password authentication system. |
