Which of the following do asymmetric cryptography systems provide? Select all that apply.1 pointAuthenticity ConfidentialityAvailability Non-repudiation

Asymmetric cryptography systems provide:

1. Authenticity: Asymmetric cryptography uses a pair of keys (public and private) for encryption and decryption. The public key is shared with everyone, but the private key remains secret. If a message is encrypted with a person's public key, only their private key can decrypt it. This ensures the authenticity of the message, as it could only have been encrypted by someone with access to the public key.

2. Confidentiality: Asymmetric cryptography ensures confidentiality because the message encrypted with the public key can only be decrypted with the corresponding private key. This means that even if someone intercepts the encrypted message, they cannot decrypt it without the private key.

3. Non-repudiation: Non-repudiation in cryptography refers to the ability to ensure that a party to a communication cannot deny the authenticity of their signature on a document or the sending of a message. If a person uses their private key to sign a document or message, they cannot later deny that they signed it because only their private key could have been used to create that signature.

Asymmetric cryptography does not provide Availability. Availability is typically a function of system design, not cryptography. It refers to the system being accessible and operational when users need it.
