Abstract(in English)	Boneh et al proposed c-secure codes that are kind of collusion secure codes. Because c-secure codes are too long to use in practical, it is required to construct a short code. Tardos provided a construction of a c-secure code which is a kind of c-secure code. In his structure, however, values of some parameters determined ad-hoc, so code length is not necessarily shortest. In this paper, in order to shorten the code length, we regarded these fixed parameters as variable, strictly examined equations that fulfilled the condition of c-secure, and evaluated the code length. The code length we get in this evaluation is not more than half length in previous evaluation [5] in small colluders. And we estimated the effect of each strict examination to code length.
