Final answer:
Asymmetric encryption is the encryption method that works on the basis of sender and receivers using different keys for encryption and decryption.
Step-by-step explanation:
The encryption method that works on the basis of sender and receivers using different keys for encryption and decryption is asymmetric encryption. In asymmetric encryption, each user has a pair of keys consisting of a public key and a private key. The sender uses the receiver's public key to encrypt the message, and the receiver uses their private key to decrypt the message.
