摘要
A method for controlling access to a shared secret includes methods (300, 400) for enrolling and disenrolling shareholders of the shared secret. The methods (300, 400) include steps which allow each shareholder to retain fixed shares associated with the shared secret while preserving the integrity of the shared secret. A method (500) for recovering the shared secret includes a step of computing (508) split shares for shareholders given a fixed share and a transmogrifier key associated with each. The fixed shares and transmogrifier keys are combined (510) for recovering the split shares which are further used when recovering the shared secret.
