Which of the following is true about asymmetric encryption? (2024)

FAQs

What is true about asymmetric encryption? ›

As the name implies, asymmetric encryption is different on each side; the sender and the recipient use two different keys. Asymmetric encryption, also known as public key encryption, uses a public key-private key pairing: data encrypted with the public key can only be decrypted with the private key.

Which statement is true of asymmetric encryption? It requires a large amount of processing power.

Asymmetric encryption involves two keys, private and public. Something encrypted with one can only be decrypted with the other. There is no shared key. A message encrypted with a key can not be decrypted with the same key.

RSA is an algorithm used by systems to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm.

Published in 1977, RSA is one of the oldest examples of asymmetric encryption. Developed by Ron Rivest, Adi Shamir, and Leonard Adleman, RSA encryption generates a public key by multiplying two large, random prime numbers together, and using these same prime numbers, generates a private key.

Security: Asymmetric encryption is considered more secure than symmetric encryption because it eliminates the need to exchange secret keys, which can be a security risk. Additionally, the private key is kept secret, which makes it harder for attackers to intercept or tamper with the data.

Which of the following statements is true of symmetric encryption? With symmetric encryption, the same key is used for both encoding and decoding.

Symmetric encryption is faster and easier to use than asymmetric encryption, but it is less secure. If the key is compromised, the data can be easily decrypted. Asymmetric encryption, on the other hand, is more secure because even if one key is compromised, the data remains safe.

Asymmetric cryptography techniques allow for extremely secure communication between two parties. Chances are, you've encountered this technology before, even if you never knew what it was called.

Asymmetric cryptography is also called public-key cryptography. It uses key pairs consisting of a public key and a private key.

What can asymmetric encryption be used for quizlet? ›

Asymmetric encryption can be used for confidentiality but not for authentication. Asymmetric encryption transforms plaintext into ciphertext.

Asymmetric encryption algorithms use two different keys for encryption and decryption. The key used for encryption is the public key, and the key used for decryption is the private key. Both the keys must belong to the receiver.

The RSA algorithm, named for its creators Ron Rivest, Adi Shamir, and Leonard Adleman, is an asymmetric algorithm used all over the world, including in the Secure Sockets Layer (SSL) protocol, which is used to secure many common transactions such as Web and e-mail traffic.

Public key cryptography, also known as asymmetric cryptography, uses two separate keys instead of one shared one: a public key and a private key. Public key cryptography is an important technology for Internet security.

Asymmetric encryption is slower than symmetric encryption because it employs two separate keys that are linked through a difficult mathematical procedure. Symmetric encryption is mostly used to transfer large amounts of data.

This way, anyone can encrypt a message with the public key, but only the owner can decrypt it with the private key. However, this also means that the private key is a valuable target for hackers who want to access the encrypted data.

However, it also has some disadvantages, including: Slower encryption and decryption: Asymmetric encryption algorithms are typically slower than symmetric encryption algorithms, especially for large messages or data.
