At the risk of being too obscure:
Meditate on the nature of names and the significance of the gesture of naming. What is a Name? Why would a Name be given, changed, spoken aloud, kept secret?
To address the original question more directly: There is no set list of purported "secret names." Names and words of power are typically handed down through spiritual/magickal lineages and groups, or received in higher states of consciousness.
Do not lose the Essence for the Name.
