Due to the lack of security infrastructures, data transmission protocols for underwater wireless communications have to use identity-based cryptography for protecting the transmitted data. However, current identity-based cryptographic schemes need to transmit vehicles' real identities along with messages. Once adversaries can get real identities of vehicles, they will be able to collect information of underwater vehicles, track them and establish attacks on them. Moreover, during data transmission, adversaries will be able to count underwater vehicles and evaluate the enemy's scale. At the same time, due to the complicated underwater environment, transmitted messages will easily be lost. Therefore, non-interactive data transmission is desired, where underwater vehicles do not need transmit additional messages for authentication and key establishment. To address these issues, we present two novel non-interactive identity-based data transmission protocols. Similar to the protocols of this field, our protocols can provide integrity and confidentiality protections for transmitted messages. However, compared to other well-known approaches, our protocols do not expose any information of vehicles' real identities and use different identities for transmitting each message. By doing so, adversaries will not be able to collect information of underwater vehicles, track them, and count them. Moreover, in our protocols, underwater vehicles can transmit messages directly, without previously sending authentication and key establishment messages, namely our protocols can achieve the non-interactivity goal. In addition, one of our protocol even permits vehicles transmitting messages without knowing any information of each other. Therefore, our protocol is quite suitable for underwater environment. Experimental results show that the proposed protocol is feasible for real-world applications.
