Hello forum members,

i am looking for a way to encrypt an char array before those data are exposed via Bluetooth.

Those encrypted data later will be processed in a secure harbor. So transporting of those are

fully transparent and no security issue so far. What is the best economic way to achieve the

encryption? Maybe an public key based encryption is sufficient?

Thank you for taking time to read this and helping me out to find a solution.

The AES256 encoding/decoding algorithms are open source. Only problem (as usual) is to safely exchange the secretkey.

Thank you for your reply.

I guess it's not a good idea to place the secret key inside the module?

The PSoC chip can be secured against reding the data from extern. This will protect the key.
