  "term": "public key cryptography (PKC)",
  "field": "Cybersecurity",
  "definition": "1. Cryptography that uses two separate keys to exchange data - one to encrypt or digitally sign the data and one to decrypt the data or verify the digital signature. Also known as public-key cryptography.\n\n2. Encryption system that uses a public-private key pair for encryption and/or digital signature.\n\n3. See public key cryptography (PKC).\n\n4. Cryptography that uses separate keys for encryption and decryption; also known as asymmetric cryptography.\n\n5. A form of cryptography that uses two related keys, a public key and a private key; the two keys have the property that, given the public key, it is computationally infeasible to derive the private key. For key establishment, public-key cryptography allows different parties to communicate securely without havng prior access to a secret key that is shared, by using one or more pairs (public key and private key) of cryptographic keys.\n\n6. A cryptographic system where users have a private key that is kept secret and used to generate a public key (which is freely provided to others). Users can digitally sign data with their private key and the resulting signature can be verified by anyone using the corresponding public key. Also known as a Public-key cryptography.\n\n7. See Asymmetric-key cryptography.\n\n8. A form of cryptography that uses two related keys, a public key and a private key; the two keys have the property that, given the public key, it is computationally infeasible to derive the private key.\nFor key establishment, public-key cryptography allows different parties to communicate securely without having prior access to a secret key that is shared, by using one or more pairs (public key and private key) of cryptographic keys.",
