Which are key features of asymmetrical encryption?
Usually, only smaller amounts of data are transmitted using this method.
Two different keys are used to encrypt and decrypt the message.
The public key is mathmatically related to the private key.

(D) Obtains the proof of identoty declared by a user.
(E) Reliability of stored and transmitted data.
(F) Concealment of stored or transmitted information
(G_ Ensures uninterupted access to the network
Encryption:
Employs block or stream ciphers to encrypt tesxt.
protects data by converting plaintext to cipher text
Should be consideredwhen transmitting sensitive information across an unsecured channel.
Can be symettrical or asymmetrical.
Select the ky features of symmetrical encryption:
Symmetrical encryption can be made more secure bi ncreasing the number of cycles in the encryption process.
The more secure the encryption, the slower the program speed.
Systemetrical encryption uses the same key to encode and encrypt data.
MATCHING
