AES [ Choose ] obsolete from the 1970's; uses just one 56-bit key symmetric algorithm; supports 128, 192, and 256-bit keys Is easily defeated by a Kasiski examination Not the worst one on this list, but you still shouldn't use it anymore asymmetric algorithm DES 3DES [ Choose ] RSA [ Choose ]
PLEASE ANSWER THE QUESTION AND EXPLAIN THE ANSWER Assume that the register %rbp is currently holding 0x7fffffffebc0. Using the following GDB dump, write out, in ASCII, the string of characters starting at -0x20(%rbp). (gdb) x/4gx $rbp - 40 0x7fffffffeb98: 0x0096620656874207 0x6f66207964757453 0x7fffffffeba8: 0x6966206568742072 0x05684000006c616e 0x7fffffffebb8: 0x0068656c6c6f2063 0x7332363100000000 Hint 1: a string of characters is an array of chars with variable length. Hint 2: 0x00 is used to mark the end of a character string in C.
Cryptography Question:
Note: The notation from this problem is from Understanding Cryptography by Paar and Pelzi. Suppose you have an LFSR with 6 state bits. The first 12 bits of output produced by this LFSR are 101011100010 = 80818283848586878889810811- The first bit produced is the leftmost bit and the bit most recently produced is the rightmost bit. a) What is the initial state of the LFSR? Please enter your answer as unspaced binary digits (e.g. 010101 to represent 85 = 0, $4 = 1, 83 = 0, 82 = 1, 81 = 0, 80 = 1). b) What are the tap bits of the LFSR? Please enter your answer as unspaced binary digits (e.g. 010101 to represent p = 0, P₁ = 1, P3 = 0, P2 = 1, P₁ = 0, Po = 1).

Consider the following binary number: 1.11000000000000000000100. What are the values of guard, round , and sticky bits after 8 right shifts? The encoding of the options is (guard)(round)(sticky). For example, if guard bit is 1, round is 0, and sticky bit is 0, the encoding is 100. 100 001 00 010 Arrange the steps involved in floating point multiplication. The first step must be at the top and the last step must be at the bottom. You can assume that the result is still normalized after rounding. Start 1 | Multiply the significands 2 E Set the sign of the result 3 | Check for overflow or underflow. If true, flag an exception, otherwise continue. 4 E Subtract bias from the sum | Add biased exponents of the two numbers 6 E Normalize the product, if needed 7 | Round the significand Done
