ABSTRACT:
A pronounceable security password is generated using a plurality of first word segment portions and second word segment portions, each of which has at least one character. A transition number, for each of the plurality of first word segment portions is identified, preferably using a Markov model. Each transition number corresponds to the number of different second word segment portions which can be combined with the first word segment portion to form a pronounceable word segment, such a word syllable. A first word segment portion is randomly selected. The selection of any one of the plurality of first word segment portions is of substantially equal probability. A second word segment portion, to which the transition number associated with the selected first word segment portion corresponds, is then randomly selected. The selection of any one of the corresponding second word segment portions is likewise of substantially equal probability. The selected first and second word segment portions are combined to form at least a part of the pronounceable security password.
