Bitstream Encryption / Decryption
7424 - [All Nexus] Lattice Radiant Programmer: Is there a default readout for the encryption key of Nexus Devices?
Description: When reading out the encryption key in Nexus device, there is a default value. Is this expected? Solution: Nexus devices have the following default encryption key values: For Crosslink-NX, Certus NX, and Mach NX: ...
6079 - MachXO3D: Why does the device could boot whether public key is programed or erased given that ECDSA authentication function is used?
MachXO3D's configuration image authentication during programming or boot does have flexible authentication support as stated below: 1. Authenticate during programming = secure + fast boot 2. Pre-authenticaion = secure + slower boot time 3. No ...
3036 - Lattice EPC2/S: Why is the encrypted bitstream not working for Lattice ECP2/S device?
For the encrypted bitstream to work in LatticeECP2/S device, ensure the following: For power-up, VCC must reach its valid minimum value before powering up VCCAUX (LatticeECP2/M “S” version devices only). Refer to LatticeECP2/M Family Data Sheet for ...
6400 - CertusPro-NX: What is the correct information or data for uncompressed bitstream?
In relation to the bitstream, it is encrypted bitstream format. Since all of the data are encrypted. Please find snippet below: // Header Frame FFFF BEB3 If you notice, there is BEB3 in the content instead of BDB3. It is a bitstream preamble that ...
1644 - LatticeECP3: Is there a recommended way of choosing AES (Advanced Encryption Standard) encryption key?
We implemented the AES (Advanced Encryption Standard) block based on its standard. Any analysis of the strengths and weaknesses of AES is performed by the standard's committee. Studies for the strength of AES encryption key have been documented by ...
7004 - MachXO3D: How does enabling AES feature decryption bits "RAND_AES" and "RAND_NOISE" impact on MachXO3D device configuration processing time?
RAND_AES and RAND_NOISE are clock randomization and random noise injection features, mainly use for Differential power analysis (DPA) resistance in Advanced Encryption Standard (AES) decryption. Both features are target for AES decryption, to prevent ...
5646 - ECP5/ECP5-5G/CrossLink: If the user wants to update the bitstream in the field and encrypt the bitstream so that it can only be used on my product, is there a solution available in the CrossLink device? If yes, in what document is it stated?
Encrypting the bitstream is only available with Lattice XP2, and ECP products. Crosslink, does not support a bitstream encryption solution on the other hand.
