Food Details

At the request of one of the crypto grad students, we will encrypt the security lunch food selection. We have picked values (a,b,c) in the range [0,250] which define a polynomial:

f(x) = ax2 + bx + c   mod 251
Along with the abstract for the t-th security lunch, we will post the value:
ct = mt + f(t)   mod 251
During the t-th security lunch of the quarter, you will learn the value mt (i.e., you will learn what food is served at the t-th lunch). After attending three security lunches, you should be able to figure out what the rest of the lunch selections for the quarter will be.

We will encode the plaintext (food selection) using the CLE 0.1 encoding.
