Symmetric encryption involves what key?
A shared secret keyand other words;Both the sender and receiver share the same key
The most popular private or symmetric key encryption is based on?
DES
Public key encryption is also known as asymmetric encryption?
Yes. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.
What is a secure encryption?
Encryption is a process of translating a message from the Plaintext, into an encoded message, called the Ciphertext. This is usually accomplished using a secret Encryption Key and a cryptographic Cipher. ss of translating a message, called the Plaintext, into an encoded message, called the Ciphertext. This is usually accomplished using a secret Encryption Key and a cryptographic Cipher.
How does asymmetric encryption provide confidentiality?
Asymmetric encryption can provide confidentiality in two ways:1) messages encrypted using the public key of the recipient can only be decrypted using the private key of the recipient - which only the recipient should possess.2) It can be used as part of a negotiation process between two users to establish a temporary shared key through a process such as the following:User A sends a challenge message to user B which is encrypted with user B's public key to initiate secure communications.User B decrypts the message and sends the correct response back to user A encrypted with user A's public keyThe two users are now authenticated to each otherAt this point A can send a proposed symmetric key to B encrypted with B's private keyAll further communications are encrypted via the shared symmetric keyIn this second scenario, the asymmetric encryption only facilitates the establishment of confidentiality via the eventually shared symmetric key by securing the initial negotiations.
How are classical encryption techniques like modern symmetric-key cipher?
In symmetric key techniques there is a single key and that key is kept secret. Symmetric key is a like a sub part of classical encryption.
Symmetric encryption involves what key?
A shared secret keyand other words;Both the sender and receiver share the same key
Which type of encryption process uses the same key for encryption and decryption?
A: Symmetric
How does symmetric key encryption work?
Symmetric encryption requires that both parties (sender and receiver) know and have the exact same encryption key. This key is used both for encrypting and decrypting the data. Using the same encryption algorithm means that only those individuals that know or have the same key will be able to read any messages encrypted by the symmetric key.
Symmetric encryption involves?
A shared secret key.
Which encryption standard uses the same key for encryption and decryption and offers low overhead?
Symmetric
What is a symmetric encryption?
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
What encryption requires both sides of an encrypted conversation to use an encrypted key to be able to encode and decode the data?
Any shared private key method - symmetric encryption.
What does the word symmetric encryption mean?
The term "symmetric encryption" refers to a form of computerized cryptography that uses a singular encryption key to guise an electronic message so that it can be sent in a secure manner.

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.
