Flexible key management IP core for in-the-field programming of secret keys
No personalization phase in a secure environment is required, nor an involvement from the chip or module manufacturer. Every application can simply program its own secret keys into Quiddikey-FLEX. The IP offers storage for an unlimited number of secret keys: device-specific or so-called ‘intrinsic’ keys and user-defined keys (e.g. with DRM info) of different lengths can be combined, supporting key lengths up to 256 bit symmetric, 512 bit ECC and 4096 bit RSA. Quiddikey-FLEX is available as purely digital logic IP to easily integrate in hardware into any process node.
When considering typical mobile use cases the Quiddikey-FLEX IP core offers secret key storage with an area efficiency of at least 5 times better than alternatives like e-fuse technology. The IP is also available in a software version and on FPGA platforms.
With Hardware Intrinsic Security (HIS), secret keys are not stored in embedded non-volatile memory but extracted from the hardware properties of a chip inside the device, like an electronic fingerprint of the device. This fingerprint extraction is only done when needed; attackers have nothing to find because no key is stored nor present in the power down state.
