c) open
I think this because when you're in an open space (such as starbucks) it's public for anyone to enter. I think.
Explanation:
Explanation:
RSA encryption is performed by calculating C=M^e(mod n).
However, if n is much larger than e (as is the case here), and if the message is not too long (i.e. small M), then M^e(mod n) == M^e and therefore M can be found by calculating the e-th root of C.
Answer:
there is lot of difference
