Block cipher modes
Explain why some block cipher modes of the operation use encryption whereas the others use both the encryption and the decryption?
Expert
Some block cipher modes of the operation use the encryption since input is set to some initialization vector and leftmost bits of output of encryption function are XORed along with the first segment of the plain text p1 in order to generate the first unit of the cipher text C1 and it is sent. However in the decryption, cipher text is XORed along with the output of encryption function in order to generate the plain text.
Explain the term triple encryption?
Specify any cryptographic keys which are used in PGP?
ACL (Access control list): In order to control the access to a particular number of users the wireless network makes use of ACL which is access control list. In this the unique address of the clients or the users are used and hence a check can be put
WEP (wired equivalent privacy): Wired equivalent privacy is capable of providing the same level of privacy as it is there in the wired network. The WEP makes use of a static key which both the access points and the clients know. The static key helps i
