This problem provides a numerical example of encryption using a one-round versionof DES. We start with the same bit pattern for the key K and the plaintext, namely:Hexadecimal notation: 0 1 2 3 4 5 6 7 8 9 A B C D E FBinary notation: 0000 0001 0010 0011 0100 0101 0110 01111000 1001 1010 1011 1100 1101 1110 1111
