In asymmetric encryption Both the sender and receiver have a private key and a shared private key?
No, both sender and receiver have a private key and a public key. It works like this: if you encrypt something with one key, you need the other to decrypt it. You give everyone a copy of your public key. When they want to send you something encrypted, they use your public key to send it. Only your private key can decrypt it, so no one else can read it. You don't give out your private key.

What Technology that scrambles information so that only the sender and receiver can read it?
Encryption (decryption).
Symmetric encryption involves what key?
A shared secret keyand other words;Both the sender and receiver share the same key
What is hushmail?
See the related link for more information. Hushmail offers secure and unreadable email to its users. It uses PGP encryption and a key management system to secure email for the sender and receiver.
C code for sliding window protocol?
#include<stdio.h> #include<conio.h> void main() { char sender[50],receiver[50]; int i,winsize; clrscr(); printf("\n ENTER THE WINDOWS SIZE : "); scanf("%d",&winsize); printf("\n SENDER WINDOW IS EXPANDED TO STORE MESSAGE OR WINDOW \n"); printf("\n ENTER THE DATA TO BE SENT: "); fflush(stdin); gets(sender); for(i=0;i<winsize;i++) receiver[i]=sender[i]; receiver[i]=NULL; printf("\n MESSAGE SEND BY THE SENDER:\n"); puts(sender); printf("\n WINDOW SIZE OF RECEIVER IS EXPANDED\n"); printf("\n ACKNOWLEDGEMENT FROM RECEIVER \n"); for(i=0;i<winsize;i++); printf("\n ACK:%d",i); printf("\n MESSAGE RECEIVED BY RECEIVER IS : "); puts(receiver); printf("\n WINDOW SIZE OF RECEIVER IS SHRINKED \n"); getch(); }
The address is used to identify the sender and receiver in an ip packet header?
That is called an IP address.
What is a procedure for encrypting and decrypting message?
A common procedure for encrypting and decrypting messages involves using symmetric or asymmetric encryption algorithms. In symmetric encryption, the sender and receiver share a secret key; the sender uses this key to encrypt the message, and the receiver uses the same key to decrypt it. In asymmetric encryption, a pair of keys (public and private) is used; the sender encrypts the message with the receiver's public key, and only the receiver can decrypt it with their private key. Implementing these methods ensures that the message remains confidential and secure during transmission.

To accurately transmit an electronic message the sender needs to know one code and the receiver needs to know a different one. what online security measure is being used?
It is the Public Key Encryption. A user using the Public Key Encryption has to have both a private key and a public key to send a secured message. The private key is used to unlock both a private and a public key encryption. A public key cannot unlock a private encryption.
What is symmetric and asymmetric?
From another user: Symmetric cryptography uses the same secret (private) key to encrypt and decrypt its data whereas asymmetric uses both a public and private key. Symmetric requires that the secret key be known by the party encrypting the data and the party decrypting the data. Asymmetric allows for distribution of your public key to anyone with which they can encrypt the data they want to send securely and then it can only be decoded by the person having the private key. This eliminates the need of having to give someone the secret key (as with symmetric encryption) and risk having it compromised. The issue with asymmetric is that it is about 1000 times slower than symmetric encryption which makes it impractical when trying to encrypt large amounts of data. Also to get the same security strength as symmetric, asymmetric must use strong a stronger key than symmetric.
What data is encrypted using a single key that only the sender and the recriver know?
The data itself does not matter in this scenario. The type of encryption used is symmetric encryption, meaning that the sender and receiver have the same key to lock and unlock the data.
How do you know the both sender and recevier the encryption key?
When data is received by the receiver , receiver send an acknowledgement. After receiving the acknowledgement from receiver , senders knows the message has been successfully sent.
What happens with symmetric encryption?
Symmetric encryption is the process of encrypting and decrypting data via a single shared key. The process begins when the sender wants to trasnmit data in a secure fashion. Unencrypted data is ciphered with the shared secret key. The encrypted data is then sent to the receiving host via the internet or local resource. Once the receiver obtains the encrypted data, the receiver uses the same shared secret key to decipher the data. The receiver then has the same exact data unencrypted as the sender. The biggest advantage besides the security is that symmetric encryption is way faster than asymmetric encryption. The disadvantage is getting the shared secret key between the two parties without being tampered with or without being seen/heard by an unauthorized host.
What is the difference between a sender receiver an a receiver sender?
The terms "sender-receiver" and "receiver-sender" typically refer to roles in communication processes. In a sender-receiver model, the sender initiates the message, while the receiver is the recipient who interprets it. Conversely, a receiver-sender model emphasizes the receiver's active role in providing feedback or responding, making them a sender as well. Essentially, the distinction lies in the focus on who initiates versus who responds in the communication dynamic.
Do private messages in facebook can be seen by others?
Private messages are only seen by the sender and the receiver. These messages do not pop up for the public.
What is the responsibility of sender and receiver?
sender is to deliver or give message while the receiver is to receive a message from the giver or sender.
Who is responsible for poor communication sender or receiver?
The idea that both the sender and receiver are responsible for listening is called
