Could anybody explain me what do smart cards producers mean giving following parameters: - RSA signature time without CRT, - RSA signature time with CRT? I know what CRT is but I don't understand what are the implications of generating signature with and without CRT (differences in security).

When the CRT is used, "p" and "q" have to be stored along with the secret key. This may be require more memory than some cards have, but there aren't any security problems with using the CRT.
