Expert Solution & Answer
Chapter 12, Problem 11RQ
Explanation of Solution
Two-phase commit protocol:
The two-phase commit protocol is used to make sure that the transaction atomicity and
The need of this protocol helps to make sure that the database changes form remote site is coincided. If not, each and every transaction is undone to sustain a consistent database.
There are two phases in two-phase commit protocol. They are,
- Preparation
- The final COMMIT
Phase 1: Preparation
- The coordinator transfers the message from PREPARE TO COMMIT to all subordinates...

We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7).
A code breaker manages to factories 247 = 13 x 19
Determine Alice's secret key.
To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.
Consider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks? Justify your answer.
