A method for exporting sensitive information an integrated circuit, the method comprising: fabricating an integrated circuit, the integrated circuit having a register-transfer level 'RTL' key fabricated in the integrated circuit, wherein the RTL key is a pre-determined cryptographic key; signing the sensitive information using the RTL key using a signature; and exporting the signed sensitive information and the signature for validation.

Sensitive information provision process

An Integrated Circuit (IC) includes an on-chip non-volatile memory (NVM) and an on-chip processor. The on-chip NVM is configured to store a representation of a device-specific part of a security certificate assigned to the IC. The on-chip processor is configured to obtain a common part of the security certificate, to reconstruct the security certificate from the obtained common part and from the representation of the device-specific part stored in the on-chip NVM, and to perform a security operation using the reconstructed security certificate.

Compact security certificate

A computing device includes a non-volatile memory (NVM) interface and a processor. The NVM interface is configured to communicate with an NVM. The processor is configured to store in the NVM at least (i) data entries including data and (ii) mapping entries including mapping information that indicate physical addresses in which the data entries are stored in the NVM, and to verify authenticity of the data entries and of the mapping entries using a hierarchical authentication scheme in which (i) the data entries include first authentication information that authenticates the data, and (ii) the mapping entries include second authentication information that authenticates both the mapping information and the data entries.
