What does the following Python code do? import serial #Import Serial Library arduinoSerialData = serial.Serial('com11,9600) #Create Serial port object called arduinoSerialData while (1==1): if (arduinoSerialData.inWaiting()>0): myData = arduinoSerialData.readline() print myData O Nothing O Read data from the serial port and plot it on an x-y graph. O Read data from the serial port and displays it on the screen. O Reads data once from the serial port and displays one piece of data on the screen.

Make a port scanner in python This is what I have so far, but I need the program to take a host as a command-line argument and the port range to scan.

Last Stage of Delirium, a security study organisation, created some clean portbinding shellcode for Linux. Shellcode that is clean is shellcode without any NULL symbols. As was already stated, NULL characters prevent the majority of buffer overflow vulnerabilities from being exploited properly because the function stops copying when a NULL byte is encountered. E

how do i apprach this problem?

The NX (“no execute”) bit can also be supported by modern CPUs. To force a CPU to avoid running the code on a file, set the NX bit to 1 on that page. Currently, the OS and paging hardware implement this maximum quantity. Keep in mind that non-X86-compliant software/hardware can be executed on an OS and hardware How about a parser who wants to enforce NX above the operating system level? The programmer inserts a nX-bit association with each memory page at the bottom (in other words, at each memory location of nX bits.) The programmer imposes a size limit of 4095 bytes for application-level data structures. each stack frame is allocated in its own page, and no stack frame is larger than a page. At a given point in time, a stack frame might look like this: |-----------------------| | | +-----------------------+ entry %esp-->| return address | +-----------------------+ new %ebp---->| saved %ebp | +-----------------------+ | buf[4] | | buf[3] | | buf[1] | | buf[0] |…

An encryption mode Accepts 3 parameters on the stack 32 bit OFFSET of a BYTE array (this array contains a 26 character key) 32 bit OFFSET of a BYTE array (this array contains the plaintext message to be encrypted) 32 bit OFFSET of a signed DWORD (the dereferenced value initially contains the integer -1) Note that the plaintext message will be in a BYTE array that ends with a NULL character (indicating the end of the message) This operational mode will encrypt the requested message. By the time your function returns, the original plaintext message array will be overwritten with the correctly encrypted message.

Objective: This project will introduce you to interprocess synchronization mechanisms in UNIX using named POSIX semaphores, pthread mutex semaphores, and pthread condition variables. You will:Use named POSIX semaphores to synchronize the producer and consumer threads. Use pthread mutex semaphores and pthread condition variables to synchronize the access to a shared buffer between producer and consumer threads. Create a fixed-sized buffer to store the encoded data generated by the producer thread. Use the buffer to store the encoded data generated by the producer thread and transfer it to the consumer thread through the shared buffer. The producer thread should read the input file and generate the Huffman code for the input data. The producer thread should then encode the input data using the Huffman code and write the encoded data to the fixed-sized buffer. The consumer thread should read the encoded data from the shared buffer and decode it using the Huffman code. The consumer thread…

Experimenting with AES-”S symmetric key cipher. Note: You may use any programming language that provided libraries for AES. Descrion: This assignment consists of two parts:PART 1: write a program that uses AES-12/1 to decrypt a message. The program should be named "decrypt", and should deal with three files that contain the encrypted text as a stream of bytes, the 128-bit key for decryption stored as a stream of bytes, and file outcome of the decryption, respectively. o To test this program, here's an example of an encrypted message a. its 128-bit secret key PART 2: you will try to use "brute force" to decrypt an encrypted message, where you only have Sirrst 96-bits of the 12S-bit secret key (last 9 bytes of the secret key are he program should be called "findk", and should deal with two files that contain the encrypted text as a stream of bytes and the first 96-bits of the key, respetively. The program should decryptedn standard the the missing h6177 of the key in hexadecimal,…
