What is the main advantage of public key cryptography over symmetric key cryptography?

Back

Public key cryptography allows for secure communication without the need to share a secret key.

Front

Explain the concept of public key cryptography with an example.

Back

Public key cryptography uses a pair of keys - a public key and a private key. An example is RSA encryption, where the public key is used to encrypt the message, and the private key is used to decrypt it.

What is the full form of RSA in the RSA algorithm?

Back

Rivest-Shamir-Adleman

Front

How does the RSA algorithm work to encrypt and decrypt messages?

Back

It uses a public key to encrypt and a private key to decrypt messages.

Front

Explain the process of encryption using the RSA algorithm.

Back

The process of encryption using the RSA algorithm involves using the recipient's public key to encrypt the message before sending it.

Front

What is the purpose of digital signatures in cybersecurity?

Back

To verify the authenticity and integrity of digital documents or messages.

Front

How does a digital signature ensure the authenticity and integrity of a message?

Back

A digital signature ensures the authenticity and integrity of a message by using cryptographic algorithms to create a unique hash value for the message, which is then encrypted with the sender's private key.

Front

What is the role of the private key in public key cryptography?

Back

The private key is used to decrypt the message.

Front

What is the main disadvantage of public key cryptography?

Back

Public key cryptography requires more computational resources than symmetric key cryptography.

What is the purpose of the public key in the RSA algorithm?

Back

The public key is used to encrypt the message.
