Based on what you said (as far as I understood) I'll suggest now the
replacement term 'a new stream encryption scheme intended to
achieve as best as possible the functionality of an ideal OTP'.
Does that satisfy all people who have sent in comments in matters
of terminology? If no, please suggest better terms. If yes, please
kindly use a text editor to do the replacement (i.e. change all
occurences of 'pseudo-OTP' to the above term) in my original post
and kindly soon contribute your discussions on the topic.

Thanking you very much beforehand,

M. K. Shen
