Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal for dynamic data encryption in a communication system is provided. The method includes receiving, from a network entity, a list of network public keys including a plurality of network public keys and corresponding key indexes, generating a pair of keys including a user equipment (UE) public key and a UE private key in response to receiving the list of network public keys, randomly selecting a network public key from the list of network public keys received from the network entity, generating a shared secret key corresponding to the UE by using the randomly selected network public key and the UE private key, and encrypting data to be transferred between the UE and the network entity by using the generated shared secret key corresponding to the UE.
