WebUsing the DES encryption algorithm E and a secret key K, a data authentication code (DAC) is calculated as follows (Figure 12.7). The DAC consists of either the entire block O N or the leftmost M bits of the block, with 16 <= M <= 64. Cipher-Based Message Authentication Code (CMAC) As was mentioned, DAA has been widely adopted in … WebFeb 17, 2024 · This memory efficient Doubly Linked List is called XOR Linked List or Memory Efficient as the list uses bitwise XOR operation to save space for one address. In the XOR linked list, instead of storing actual memory addresses, every node stores the XOR of addresses of previous and next nodes. Consider the above Doubly Linked List. The XOR operator is extremely common as a component in more complex ciphers. By itself, using a constant repeating key, a simple XOR cipher can trivially be broken using frequency analysis. If the content of any message can be guessed or otherwise known then the key can be revealed. Its primary merit is that it is simple to implement, and that the XOR operation is computationally inexpensive. A simple repeating XOR (i.e. using the same key for xor operation on the whole da… crystal berryman
