| Summary: | There is about 6 × 10^15 eight-character strings from Czech small and capital letters and numbers. The vast majority of such passwords is impossible to remember because of no association with any “reasonable” contents. In this paper we come to an estimate that the number of meaningful Czech sentences containing 4–5 words is certainly by several decimal orders higher (even without distinguishing small and capital letters), and passwords created in this way are easy to remember. Further we show some simple ways to extend the “space” of such passwords up to ca. 10^40 theoretically possible strings without significantly complicating the possibility to remember the chosen password. A method for efficient generation of strong passwords is thus offered. |
