摘要： A method for data security includes receiving, in a processor having a one-time programmable (OTP) memory, which includes multiple bits and has a current state defined by the bits of the OTP that have been programmed, new information to be written to a data memory. Based on the new information and the current state, at least one further bit of the OTP memory is selected to be programmed, thereby defining a new state of the OTP memory. A new digital signature is computed over the new information and the new state. The new information and the new digital signature are saved in the data memory. After saving the new information and the new digital signature in the data memory, the at least one further bit of the OTP memory is programmed, whereby the new state becomes the current state. Related apparatus and methods are also disclosed.
