There is described a chip comprising a one-time programmable (OTP) memory programmable to store chip configuration data, and a verification module operable to access the OTP memory. The verification module is operable to receive a verification request relating to a specified portion of the OTP memory, the verification request comprising mask data defining the specified portion of the OTP memory. In response to the verification request, the verification module is operable to use the mask data and the OTP memory to generate verification data relating to the specified portion of the OTP memory, the verification data further being generated based on a secret key of the chip. There is also described a chip-implemented method of generating verification data relating to a specified portion of a one-time programmable (OTP) memory of the chip. There are also described methods for primary or secondary verification systems to verify a configuration of a specified portion of the OTP memory the above mentioned-chip. |
