Public Key and Private Key in cloud computing refer to a pair of cryptographic keys used for encryption and decryption or to create digital signatures.

• The public key is made available to everyone, while the private key is kept secret.
• Together, they enable secure communication over insecure networks and verify the identity of a user or device.

Public Key and Private Key work together to enable secure communication and verify identities.

• The public key is used to encrypt data, and the corresponding private key is used to decrypt it.
• In digital signatures, the private key is used to create the signature, and the public key is used to verify it.

A cloud service provider, CloudServe, uses public key and private key pairs to secure communication with their customers. When a customer wants to send sensitive data to CloudServe, they encrypt it with CloudServe's public key. Only CloudServe, with their private key, can decrypt this data. This ensures the data remains secure during transmission.
