Devise an algorithm that generates an access control matrix A for any given history matrix H of the Chinese Wall model. A significant portion of the grade for this problem involves your justification of your algorithm.
Consider using mandatory access controls an compartments to implement an ORCON control. Assume that there are k different organizations. Organization i will produce n(i,j) documents to be shared with organization j.
a) How many compartments are needed to allow any organization to share a document with any other organization? Show your work.
b) Now assume that organization i will need to share nm(i,i1,...,im) with organizations i¬1,...,im. How many compartments will be needed? Show your work.
