In this paper, a key assignment scheme whose securityis based on solving discrete logarithms is proposed to workout a solution on the access control problem in an arbitrarypartially ordered user hierarchy. Each user is assigned asecret key used to efficiently derive his successors' secretkey and assigned an encryption key at the same time used toencrypt his information items or files only. Thus, any usercan freely change his own encryption key for some security reasons without caring about those security classes withlower clearances to make their information items been re-enciphered. And moreover, make a security class be addedinto or deleted from the hierarchy without changing any issued keys.
