What is the Public Key Encryption?
Rating:
The Public Key Encryption also called asymmetric encryption was first publicly proposed by Diffie and Hellman in 1976. Public Key Encryption is more secure than non-public key encryption. It is based on the mathematical functionality rather than on the simple operations on bit patterns. It uses two separate keys. It has five stages as follows:
- Plain Text: It is the original message.
- Encryption Algorithm: It performs different transformations on plain text.
- Public and Private Key: It is the input to the encryption algorithm.
- Cipher Text: It is the scrambled message as an output.
- Decryption Algorithm: It performs on cipher text and gives the original message as an output.
