comment plaintext distribution ,perfect secrecy cryptosystem
I'm not sure that the claim actually holds. Are you sure that there are no additional constraints on the "specific plaintext distribution"? Unless I'm confused, any encryption scheme (or even the identityfunction) offers perfect secrecy for the distribution that has probability 0 for all but one plaintext. But obviously this does not imply perfect secrecy for other distributions.
