There's no clear information about the origin of 'the secret name of ra story'. It might have emerged from a group of people interested in Egyptian mythology, like a small community of storytellers or writers. They could have combined different elements of Ra's mythology, such as his power, his role in creation, and the importance of names in ancient Egyptian culture, to come up with this story.
