The inclusion of the salt in the unix password scheme increases the difficulty of guessing by a factor of 4096. but the salt is stored in plaintext in the same entry as the corresponding ciphertext password. therefore, those two characters are known to the attacker and need not be guessed. why is it asserted that the salt increases security?

Problems: 1. using textbooks, reference books, and internet as your source of research, draw the following microprocessor microarchitectures i. intel 8086 ii. motorola 68000 i atmel atmega32 iv. mips single cycle v. arm cortex-m3 write an hdl module for a hexadecimal seven-segment display decoder. the input is 4-bit binary representing a hex number (0-f), and the output is 8-bit seven segment display bits (a-h). thus, the decoder must handle the digits 10 - 15 to display a-f respectively, in addition to 0-9 numbers. 2. design a 4-bit left and right rotator (both outputs). first sketch schematic diagrams of your design. then implement your design using hdl coding. 3. 4. design a modified priority encoder that receives an 8-bit input, a7: 0 and produces a 3-bit output, y2o. y indicates the most significant bit of the input that is true. y should be 0 if none of the inputs are true. give a simplified boolean equation, sketch a schematic, and write an hdl code. 5.write an 8: 1 multiplexer module called mux8 with selection inputs s, data input d, and data output y. data input (d) and data output (v) are 32-bit wide

Which of the following statements tests if students have a grade of 70 or above, as well as fewer than five absences? a: if(grade > = 70 and daysabsent < = 5): b: if(grade > = 70 or daysabsent < = 5): c: if(grade > 70 and daysabsent < = 5): d: if(grade > 70 or daysabsent < = 5): i took the test the answer is a

Consider the following statements, then select one of the answers below: the signal() function shown below registers "sig_handler()" as the signal handler function for the sigkill signal, without the complexity of using when the sigkill signal is sent to a process running this code, by a user typing "kill -kill ", where the correct process id is used for to target the process, sig_handler() will be executed.
