public key cryptography
Public key cryptography is a secure method of communication that relies on a pair of cryptographic keys: a public key and a private key. The public key is widely distributed and used for encryption, while the private key remains secret and is used for decryption.
This technology ensures confidentiality, integrity, and authentication of digital information.
Its use is justified due to its ability to establish secure communication channels without the need for pre-shared secrets, enabling secure transactions, data protection, and secure authentication.
