Have you ever heard about Public Key cryptography? If not, this article is for you. Today we will talk about what is meant by public key cryptography and the risks of Public Key. Let’s find out by reading the article below.
What is meant by public key cryptography?
Public key cryptography (PKC) is an encryption technique that uses paired public and private key (or asymmetric key) algorithms for secure data communication. The message sender encrypts the message using the recipient's public key. To decrypt the sender's message, only the recipient's private key can be used.
The two types of PKC algorithms are RSA (an acronym named after the algorithm's inventors, Rivest, Shamir, and Adelman) and Digital Signature Algorithm (DSA). PKC encryption continues to evolve to meet the growing need for secure communications across multiple sectors and industries, such as the military.
PKC is also known as public key encryption, asymmetric encryption, asymmetric encryption, asymmetric cipher, asymmetric key encryption, and Diffie-Hellman encryption.
The risks of Public Key
Security: If an attacker discovers your private key, he or she can read all your messages.
Possibility of losing your private key: If your private key is lost, you will not be able to decrypt received messages.
Works slowly: Because this method is slower than symmetric cryptography, it is not suitable for decrypting bulk messages.
The public key is not authenticated: no one is sure that the public key belongs to the individual it specifies, so users must verify that their public key really belongs to them.
I hope this article will help you to learn what is meant by public key cryptography and the risks of Public Key. The main advantage of this type of cryptography is that it increases data security. Because users never need to transmit or reveal their private keys to anyone, public key cryptography remains the most secure protocol.
