1. Determine the entropy associated with the following method of generating a password. 1 Mark Choose, and place in this order, one lower case letter, following by one upper case letter, followed by two digits, followed by @, followed by two letters, each upper or lower case, and then followed by three symbols drawn from the set {$,9,5,v,w,J}. Finally, apply the hash function Tiger to give an output string in hex which will be used as a password. Assume random choices are made with equal likelihood of each symbol from the space being chosen from. So for a random digit there are 10 possibilities, each chosen with probability 1/10.

 

2. Generate a BLP lattice–structured system where the objects and subjects are appropriately levelled to give access consistent with the access control matrix below. You need to describe the process by which you obtain your lattice. R and W correspond, respectively, to read and append. You are to use only the mandatory BLP rules, and a default allow in place of the discretionary rule. Be sure to add a level as necssary to ensure this is a lattice.
