problem1) Assume that we have a system with the following needs: data needs to be stored long-term in a way that it is publically accessible (e.g. anyone at all can access the data) but the integrity of the data needs to be protected as a very high priority. Find a cryptographic solution that addresses this issue, and find a solution that does not use cryptography. Which solution is better?
problem2) A) Decrypt the following (show your work):
B) Decrypt the following (show your work):
