35. A processing system for generating a pronounceable security password using a plurality of first word segment portions, each having at least one character, and a plurality of second word segment portions, each having at least one character, with each of said plurality of first word segment portions (i) having an associated set of one or more said second word segment portions, each said second word segment portion within said associated set being different from others within said associated set and being combinable with said associated first word segment portion to form a pronounceable word segment and (ii) having a transition number corresponding to the number of said second word segment portions within the associate set of second word segment portions, comprising: means for storing (i) the plurality of first word segment portions, (ii) the plurality of second word segment portions, (iii) the transition number associated with each of said stored first word segment portions and (iv) a first threshold transition number; means for retrieving one of said stored first word segment portions, wherein retrieval of any one of said stored first word segment portions is of substantially equal probability; means for retrieving one of said stored second word segment portions from the set of said stored second word segment portions associated with said retrieved first word segment portion, wherein retrieval of any one of said stored second word segment portions within said associated set of stored second word segment portions is of substantially equal probability; means for combining said retrieved first word segment portion and said retrieved second word segment portion to form a first pronounceable word segment; and means for generating a pronounceable security password including said first pronounceable word segment only if consecutive characters of said first pronounceable word segment fail to correspond to those of said first word segment portions within said plurality of first word segment portions having a transition number less than the stored first threshold transition number.
35. A processing system for generating a pronounceable security password using a plurality of first word segment portions, each having at least one character, and a plurality of second word segment portions, each having at least one character, with each of said plurality of first word segment portions (i) having an associated set of one or more said second word segment portions, each said second word segment portion within said associated set being different from others within said associated set and being combinable with said associated first word segment portion to form a pronounceable word segment and (ii) having a transition number corresponding to the number of said second word segment portions within the associate set of second word segment portions, comprising: means for storing (i) the plurality of first word segment portions, (ii) the plurality of second word segment portions, (iii) the transition number associated with each of said stored first word segment portions and (iv) a first threshold transition number; means for retrieving one of said stored first word segment portions, wherein retrieval of any one of said stored first word segment portions is of substantially equal probability; means for retrieving one of said stored second word segment portions from the set of said stored second word segment portions associated with said retrieved first word segment portion, wherein retrieval of any one of said stored second word segment portions within said associated set of stored second word segment portions is of substantially equal probability; means for combining said retrieved first word segment portion and said retrieved second word segment portion to form a first pronounceable word segment; and means for generating a pronounceable security password including said first pronounceable word segment only if consecutive characters of said first pronounceable word segment fail to correspond to those of said first word segment portions within said plurality of first word segment portions having a transition number less than the stored first threshold transition number. 41. A system for generating a pronounceable security password according to claim 35, wherein said said pronounceable security password forms a part of a private key associated with a cryptosystem.
