What are the advantage and disadvantage of public key cryptography?

Security is easy as only the private key must be kept secret. Maintenance of the keys becomes easy being the keys (public key/private key) remain constant through out the communication depending on the connection.

What are applications of public key cryptography?

The main applications of public key cryptography are considered are Digital Signature and Data Encryption. The encryption application provides the confidentiality and integrity security services for the data. The public key maintains the security services such as authentication and non-repudiation.

What are the features of public key cryptography?

Public-key cryptography, or asymmetric cryptography, is an encryption scheme that uses two mathematically related, but not identical, keys – a public key and a private key. Unlike symmetric key algorithms that rely on one key to both encrypt and decrypt, each key performs a unique function.

What is the main advantage of public key cryptography when compared to private key cryptography?

The primary advantage of public-key cryptography is increased security and convenience: private keys never need to transmitted or revealed to anyone.

What are advantages and disadvantages of RSA?

Moreover, RSA algorithm uses the public key to encrypt data and the key is known to everyone, therefore, it is easy to share the public key. The disadvantages include; RSA algorithm can be very slow in cases where large data needs to be encrypted by the same computer.

What are two different uses of public key cryptography related to key distribution?

4.8 What are two different uses of public-key cryptography related to key distribution? The public key of the recipient can be used to encrypt the message, which is in turn decrypted using a private key. Secondly, public key cryptography is used as digital signatures.
