What is Public key cryptosystem authentication and secrecy?
Public key cryptography involves a pair of keys known as a public key and a private key (a public key pair), which are associated with an entity that needs to authenticate its identity electronically or to sign or encrypt data. Each public key is published and the corresponding private key is kept secret.
How can we use Public key cryptosystem to provide secrecy and authentication?
Public key cryptography uses a pair of keys to encrypt and decrypt data to protect it against unauthorized access or use. Network users receive a public and private key pair from certification authorities. If other users want to encrypt data, they get the intended recipient's public key from a public directory.
Is public-key cryptography same as secret?
In this, the same key (secret key) and algorithm are used to encrypt and decrypt the message. In public-key cryptography, two keys are used, one key is used for encryption, and the other is used for decryption. 3. In private key cryptography, the key is kept a secret.
What are the two basic principles of Public key cryptosystem?
Principles of Public Key Cryptosystem. There are two basic principles of any cryptosystem i.e. confidentiality and authenticity.
