Any updates on the availability of an app note and/or example app demonstrating the RSA capabilities of the BCM20737?
In the absence of an app note, I do have a couple questions on how RSA is implemented. What's the recommended approach to store the private key? The 20737's NVRAM is external and insecure with nothing to prevent someone from extracting a private key stored within. If the private key is stored in RAM then a new key pair must be generated each time the part is reset or emerges from deep sleep (HIDOFF). Can anyone comment?
First off, I wanted to note that the Secure OTA Feature leverages the RSA Library, so the library is indeed functional.
However, you are correct - a private key cannot be securely stored in the 20737.
