Public Key Cryptography on CC2640

Other Parts Discussed in Thread: CC2640

Has anyone tried using Public Key Cryptography on CC2640 ?

In my App I want to receive signed messages from my server which need to be verified by the BLE device and in addition to this I want to implement signed OAD firmware whose signature will be verified on the device before updating.

Can anyone share any numbers on how much time it takes and impact on battery ? Also are there any TI recommended libraries ?

    Hi Vivek,

    There are no TI PKC examples for BLE/CC2640, but you could implement this based on some freely available C code. Note that you would want to optimize for CM3 implementations, which may be challenging. If I run across any 3rd parties that have done embedded PKC implementations, I'll update the thread.

    Please do share your findings with the community!

    Best wishes
