Kim wants to send $1 to Kyle anonymously. She has an online account with AnonyCash.com, an online bank. The bank has a public key of (33,3) and a private key of (33,7). She creates two serial numbers 0 and 1. She also creates two random numbers 2 and 1, and assigns them to the two serial numbers, respectively. For simplicity, assume that the format of the sample is "sa" where "s" is the serial number and "a" is the amount in $. For example, for a serial number 5 with $4 amount the sample is "54". All arithmetic is modulo 33. i. Show the two samples created by Kim and sent to its banker. ii. Assuming that the banker decided to inspect sample 2, show the interactions between the banker and Kim. ii. What is the content of the E-cash that Kim sends to Kyle?
