Abstract:
1. A method of securing data in a data processing device having an encryption device for encrypting and decrypting data using an encryption key-password pair, comprising the steps of: a key generating device of the data processing device generating a first encryption key by providing a first password and a first key, seed, and deriving the first encryption key from the first password, the first key seed, and a current key; the key generating device storing the first encryption key in a first location in a memory; the key generating device generating at least one redundant encryption key corresponding to the first encryption key; the key generating device storing each of the at least one redundant encryption key in a memory in a distinct location; and storing, at a register in the data processing device, the memory location of each of the first encryption key and the at least one redundant encryption key, wherein to encrypt or decrypt a first set of data the first encryption key is retrieved by an encryption device comprised in the data_processing device but upon the occurrence of a particular event one of the at least one redundant encryption key is retrieved.
