Public Key Cryptography & explain about it
PKC full form is Public Key Cryptography which is a group of algorithm-based cryptographic protocols. Two distinct keys are needed for this type of cryptography: a secret or private key and a public key. Data is encrypted and decrypted using a pair of keys in public key cryptography to prevent unwanted access or use. Certification authorities provide a public and private key pair to network users.
Other users must obtain the intended recipient’s public key from a public directory in order to encrypt data for them. The recipient receives the message once it has been encrypted using this key. When the communication is received, the recipient uses a private key that no one else has control to decrypt it.

Speed is frequently mentioned as the biggest problem with public key cryptography. The existing public key encryption approach is significantly slower than a number of private key cryptography techniques. Combining public key cryptography with secret key systems can help solve this problem by providing both the security benefits of a public key system and the performance of a secret (private) system.
Public key cryptography faces additional difficulties because it has historically been vulnerable to attacks involving falsified or hacked certification authorities. Cybercriminals that carry out these attacks choose a public key certificates from the authority that has been compromised, allowing them to pass as almost anyone.
Benefits of Public Key Cryptography
- The fundamental advantage of public key cryptography is the improved data security it offers.
- Because users never need to communicate or divulge their private keys to anyone, public key cryptography continues to be the most secure protocol
- Additionally, public key cryptography offers irrefutable digital signatures.
- In order to use public key cryptography, each user must take responsibility for safeguarding his private key.
- It is possible to understand that PKC full form is Public Key Cryptography has basic benefits.
