Answer:
Smart
Explanation:
The RFID or the radio frequency identification is an electronic device that stores information electronically. It stores and makes available the information which is stored electromagnetically, once the user is authenticated.
This technology is implemented in market places and other individual activities. It is implemented in cards called smart card for ease of payment transaction and promote online commerce (e-commerce). It is also implemented in smartphones.
Answer:
Kasiski’s method for determining 't' works for Vigenère cipher as well. The only difference is therefore in the second stage of the attack. In the second stage, one needs to build a frequency table for each of the 't' keys, and carry out an attack like on the mono-alphabetic cipher. Given a long enough plaintext, this will work successfully.
Explanation:
Kasiski method is a method of attacking polyalphabetic substitution ciphers such as Vigenère cipher. It is also called Kasiski test or Kasiski examination.
The method involve finding the length of the keyword and then dividing the message into that many simple substitution cryptograms. Frequency analysis could then be used to solve the resulting simple substitution.
Answer:
war gaming
Explanation:
Wargaming in hacking is a cyber security challenge where competitors must exploit or defend a loophole/vulnerability in a system or application or gain or prevent access to a particular computer system, it is in a form of competition but it really helps them in securing systems/application when it arises.
Answer:
provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified
Explanation:
I am assuming the programming language is Java. Actually, none of the answers are 100% correct, but this one is the only one that is partially correct. The reason is the class implementing an interface can be abstract, and in this case it may not provide ALL nondefault methods.
