BLE broadcast with digital signature or encryption (asymmetric)

[MLai]

Hi all,

I am wonder is there any way to broadcast data using asymmetric encryption algo or digital signature? As I want to encrypt my data using a key and other device to decrypt my data using another key. I had used aes and hmac for this step before, but as they are using symmetric key, they can't solve my problem anymore. Thanks a lot.

Best regards,

MLai
