Device-to-Device (D2D) communication is integral to modern wireless networks, facilitating direct communication between proximate devices without relying on base stations. Yet, securing and ensuring the trustworthiness of D2D communication presents substantial challenges. In this mini review, we delve into recent progress in securing D2D communications, focusing on approaches such as leveraging multiple trust levels, implementing adaptable data access controls, deploying resilient trust evaluation methods, and assessing performance through security proofs, analysis, and simulations.
