An implementation of the DES (data encryption standard) encryption mechanism must be built and then used to encrypt the plaintext strings given below (with defined keys). 1)work on the key generation aspects of the work 2work on the s-box generation 3work on the Permutation 4)And to works on the “ framework?? for the algorithm operation; eg inputting key, plaintext etc. OUTPUTS Student report must include detailed design and software for the DES implementation. It must also include the ciphertext resulting from the following encryption operations: PLAINTEXT KEY [login to view URL] 0123456789ABCDEF [login to view URL] 0123456789ABCDEF HINTS Various operations, which are required in order to implement the DES algorithm are supported by MATLAB. Of particular use are: 1) A means of reordering the elements of a matrix 2) Assume that X is one dimensional array represented as a matrix. X(1) is the first element of the array and X (n) is the nth. The matrix is therefore: X(1), X(2), X(3),………………. X(n-1), X(n). If r(n) is recording matrix: r(1), r(2), r(3)…………r(n-1), r(n). Then y=X(r ) will reorder the elements in X according to the indexing values in r. EG: let X=6,7.8, let r= 2,1,3 then if y=X(r), y=7,6,8 3) Structures can be built to rotate the elements of a matrix to the left or to the right. Assume that X is matrix as above: Let y=X with elements rotated one place to the right: Y=[X(n),X(1:n-1)], Similarly, with all elements rotated one place to the left Y=[X(2: n), X(1)]
