ABSTRACT:
A method and apparatus for secure storage of data by using redundant keys is provided. The method includes encrypting a data set by using a master key, which can be encrypted by different sync keys. Sync keys can be generated by different supervisor cards. Thereafter, the encrypted master key and the encrypted data set can be stored in a memory. Further, credentials stored in one of the supervisor cards can be encrypted and transferred to other supervisor cards, to provide redundancy of supervisor cards.
