Write a Java code that contains:
-develop a TCP secure socket and successfully transmit packets
between two computers (server & client)
-Authentication & Confidentiality service is Apply in this code
Step by step
Solved in 2 steps
- Please solve it correctly and please provide explanation of your answers. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. (a) What will be the sequence number of the third TCP handshake signal send from PC to webserver?…Computer Science Write TCP Send/Receive methods for text-based communication which uses the “$>!!$>” as the boundary pattern for messages. You can use Helper classes to ease your pseudo code.Write a Fixed Size message Send and Receive Pseudo Codes (you can also use C#) for TCP Communication. Fill only the insides of the functions. Unnecessary parts are not assessed (i.e. sockets are ready). Public byte[] SendFixData(Socket s,…) { * Fill the code* for sending fixed size messages* in Tcp Communications } Public byte[] ReceiveFixedData(Socket s,….) { * Fill the code * for receiving fixed size messages * in Tcp Communications}.
- Description: You are required to implement a server program that responds to both TCP and UDP requests from the corresponding clients. The service provided by the server is simply a substitute cipher/cryptosystem. The cipher replaces one character to another based on some key. The input message (plaintext) can be of any size but composed only of small-letter (abcdefghijklmnopqrstuvwxyz). The output (ciphertext) has the same size and composed also of small-letter characters. The key is limited to 7 characters (also small-letter). You need to treat each digit as a number according to its position in the alphabet. For example, a=0, b=1, …,z=26. To encrypt a message, you add a plaintext character with the corresponding key character (mod 26). The key might be repeated to match the length of the plaintext message. In the decryption, you subtract the corresponding key character from the ciphertext character (mod 26). Again the key might be repeated as necessary. For example, if the…n this assignment, you will develop a simple socket-based TCP program in C++ for a server that accepts lines of input from a client and prints the lines ontothe server’s standard output. Compile and execute your program. On any other machinethat contains a Web browser, set the proxy server in the browser to the host that isrunning your server program; also configure the port number appropriately.Your browser should now send its GET request messages to your server, and yourserver should display the messages on its standard output.Use this platform to determine whether your browser generates conditional GETmessages for objects that are locally cached Create an informal reportWrite TCP Send/Receive methods for text-based communication which uses the “$>!!$>” as the boundary pattern for messages. You can use Helper classes to ease your pseudo code.
- 1. Part A: • Develop a TCP server program in java that waits for clients to connect. • The server responds to the client with one of the following based on client’s request: *Export public key generated using KeyPairGenerator *Export Message Digest * Export Digital Signature * Send original text for the encrypted text received from clientWrite TCP client and server that can communicate to each other saying "Hello I am client and My id is 1" and "Hello I am server. Your received id is 1" The ID of the client should be only a single-digit i.e from 0 to 9 Run one client and server on same machine Your server should be in running state infinitely and should not terminate after serving one client only. The clients will keep on coming one by one and server will keep on serving them unless terminated intentionally. Sample Test Bench - Client1 sends: "Hello I am client and My id is 1" - Client2 sends: "Hello I am client and My id is 2" - Server response on client1: "Hello I am server. Your received id is 1" - Server response on client2: "Hello I am server. Your received id is 2"Part A: Develop a TCP server program in java that waits for clients to connect. The server responds to the client with one of the following based on client’s request: Export public key generated using KeyPairGenerator Export Message Digest Export Digital Signature Send original text for the encrypted text received from client Part B: Develop a TCP client program that request from TCP server developed (in Part A) public key, Message Digest, Digital Signature and original text by sending the encrypted text. TCP client will display the various objects received from TCP server on its console.
- Write this program in Python. Your task is to implement both the server and client parts of a chat program. You must use TCP sockets to provide the following functionality: The server should allow for multiple simultaneous clients (Multithread). Any client can get a list of all other connected clients from the server. The server should provide both clients sending to individual other clients, and clients sending to all other online users -- simultaneously. The server should support some other functionality like groups, where clients can join groups tracked by the server, and messages can be sent to all clients in the group. Other option to send files to other clients. Each client must have an ID; used for connecting with the server, in order the server can keep a list of all connected clients. The client should access all functionality that the server supports. Therefore it must be able to request a list of the IDs for all other connected clients, send messages to other individual…use python Type in a client script that will establish a TCP connection with a server, then send a message ("Hi"), and receives a message from the server. The client should print out the received message. Assume that the server is using port number 51234 and is located at a machine with an IP address "192.168.7.12".Tasks: Part A: Develop a UDP/IP server program in java that waits for clients to server. The server responds to the client with one of the following based on client’s request: Export secret key generated using KeyGenerator Export Text and Message Digest Export Text and Digital Signature Send original text for the encrypted text received from client Part B: Develop a UDP/IP client program that make request secret key, Message Digest, Digital Signature and original text by sending the encrypted text to server program developed (in Part A). This program will display the various objects received from server on its console.
