Discuss how the asymmetric encryption algorithm can be used to achieve the following goals.
a. authentication: the receiver knows that only the sender could have generated the message.
b. secrecy: only the receiver can decrypt the message.
c. authentication and secrecy: only the receiver can decrypt the message, and the receiver knows that only the sender cosssuld have generated the message.

Technician a says that a shop towel should never be used to clean around the flange area before replacing an automatic transmission filter. technician b says that a dimpled transmission fluid pan can be repaired. who is right

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.
