Consider a simple symmetric encryption algorithm as follows 1- input text t and 64 bit key k 2- divide t into 64 bit size blocks b1.bn 3- get first block b1 and perform bit-wise xor with k to?
Mmot8
1- Input text T and 64 bit key K and initialization vector IV
2- Divide T into 64 bit size blocks B1...Bn
3- Get the first block B1 and perform bit-wise XOR with IV to
produce scrambled plaintext
4- Get the scrambled plaintext and encrypt with K with DES to
produce encrypted block E1
5- Repeat
a. Get next block Bi and perform bit-wise XOR with Ei-1 to
produce scrambled plaintext
b. Get the scrambled plaintext and encrypt with K with DES
to produce Ei
6- Until End of Text

How many bitwise operators are present in Java?
The bitwise & operator performs a bitwise AND operation. The bitwise ^ operator performs a bitwise exclusive OR operation. The bitwise | operator performs a bitwise inclusive OR operation.
All the bitwise operators have the same level of precedence in Java true or false?
False: highest precedence & bitwise AND ^ bitwise XOR | bitwise OR lowest precedence
How do you represent assignment by bitwise XOR operator?
The bitwise XOR operator is ^, or shift 6. The bitwise XOR assignment operator is ^=.
What is the use of bitwise operator in c plus plus?
They perform bitwise operations like AND (&), OR (|), XOR (^) and NOT (~).
How do you write a javascript to swap two numbers without using third one?
By using the algorithm of bitwise EORing (Exclusive ORing) the numbers together:If the two numbers are X and Y, then to swap them:X = X EOR YY = Y EOR XX =X EOR Ywill swap them.With knowledge of that algorithm, one then uses the syntax of Javascript to implement it.
What is use of l in c language?
Bitwise OR.
What are Bit Manipulations in C programming?
in C you can manipulate the individual bits of a data item. << leftwise shift >> rightwise shift & bitwise AND | bitwise OR ~ bitwise complement (flips all bits) I can't go intoa tutorial here in how to use these, but google it - i just did and there's tons of info out there.
What are different type's operators?
The different types of operators are as follows: *Arithmatic operator *Relational operator *Logical operator *Assignment operator *Increment/Decrement operator *Conditional operator *Bitwise operator *Special operator
Explain the Difference between bitwise operator ' and ' and address operator ' and ' of pointer?
The bitwise logical operator and (&) calculates the bitwise logical and of two integral values. It is a binary operator.The address of (&) operator returns the address of the value to its right. It is a unary operator.The distinction between the two is one of context. The logical and operator will follow (and be preceeded by) a value, while the address of operator will follow an operator.
Which bit wise operator is suitable for putting on a particular bit in a number?
bitwise OR is used..
Which bitwise operator is suitable for turning off a perticular bit in a number?
AND, or to be more precise: OR
What are logical classes in c plus plus?
There is no such thing. Logic is bitwise operation, not a data type.
