Asymmetric encryption is a cryptographic system that uses a pair of keys, a public key for encryption and a private key for decryption, ensuring secure communication over an insecure channel. It enables secure data transmission and authentication by allowing only the intended recipient with the private key to decrypt the message encrypted with the public key.

A public key is a cryptographic element used in asymmetric encryption systems, allowing users to encrypt messages or verify signatures without exposing the private key. It is essential for secure communication, enabling the establishment of trust and confidentiality in digital interactions.

A private key is a cryptographic tool used in asymmetric encryption that allows the owner to decrypt messages and sign transactions, ensuring confidentiality and authenticity. It must be kept secret to maintain the security of the encryption system, as anyone who possesses the private key can impersonate the owner.

private key

Secure communication ensures that information shared between parties remains confidential, authentic, and integral, protecting it from unauthorized access and tampering. It employs cryptographic techniques to safeguard data during transmission, ensuring that only intended recipients can access and understand the message content.

Authentication is the process of verifying the identity of a user, device, or system, often serving as the first line of defense in cybersecurity. It ensures that access to resources is granted only to those who have been properly identified and authorized, thereby protecting sensitive information from unauthorized access.
