Patent abstract
A method is provided for generating a new instance of an N-bit cryptographic key for storage in a non-volatile memory (NVM) in which unprogrammed cells have a particular binary value. The method includes generating a random N-bit updating sequence, and generating the new instance of the N-bit cryptographic key by negating each bit in a current instance of the N-bit cryptographic key that has the particular binary value and differs from a correspondingly-positioned bit in the random N-bit updating sequence, without negating any bits in the current instance of the N-bit cryptographic key that do not have the particular binary value. Other embodiments are also described.
