DescriptionWritten AssignmentCryptographyYou have been selected to be the leader of a Secret Spy Team! As a mathematician in training, your expertise with functions will be helpful in securing top secret communications between your team members. Your teams goals and objectives are to encode secret messages with details on your next teams meeting. As Team Leader you are to help train the team to use functions to encode the messages making them unreadable to anyone outside of your team.Each letter of the alphabet and a blank space can be represented as a two-digit number.Numerical Look-Up Table:A = 1B = 2C= 3D = 4E = 5F = 6G = 7H = 8I = 9J = 10K = 11L = 12M = 13N = 14O = 15P = 16Q = 17R = 18S =19T = 20U = 21V = 22W = 23X = 24Y = 25Z = 26Space = 27Pick an encoding/decoding pair of functions from the list of functions. These inverse functions are the keys to encoding and decoding your teams messages.Encoding A Message:a) First part of message: Using the chart below, replacing the word first name in the chart with your first name, and the Numerical Look-up Table, represent the following message numerically. Once you convert the message to numerical form, use the encoding function you selected from the list to make the message secret. THIS IS FIRSTNAME b) Second part of message: Pick one of the following to coordinate your teams secret meeting. Write a short message to the team of four words or less. Encode the message using the numerical lookup table and coding function. Location: Decide on a location to meet. For example, MEET AT STARBUCKSWhere to Be: Decide where to be at the location. For example, SIT BY THE DOORTime: Decide on the time to meet. For Example, MEET AT NOONWhat to Bring: Decide on what to bring. For example, BRING THE MAPWhat to Wear: Decide on what each team member should wear. For example, WEAR A STOCKING CAPWhat to Do: Decide on what to do at location. For example, BUY A COFFEEPassword to Say: Decide on password to say for meet up. For example, I LIKE TEAPassword to Reply: Decide on password to reply for meet up. For example, I PREFER SODAc) Contribute to the teams goal by sharing your encoded message (part a and part b) As the Team Leader, explain all steps to train your team for coding the secret meeting messages.
