Create a digital interface design featuring a central symbol representing digital currency, surrounded by various futuristic icons representing data security, communication, and technology. Change the central symbol to a stylized "D" and modify the surrounding icons to include elements like a shield (for security), a cloud (for data), and a network node (for connections). Use a dark background with glowing blue and green accents, and incorporate light trails that suggest motion and connectivity. Remove any brand references or identifiable logos.
