BTLE Examples

BTLE / Lightweight Secure Transport Example:

Bluetooth Low Energy (BTLE) is a lightweight / low power wireless protocol. Its supported by Apple iPhone 4s and later and most Android phones. It operates in the 2.4GHz spectrum and has 3 advertising channels and 37 data channels.

Elliptic Curve Integrated Encryption Scheme (ECIES) Example

wolfSSL ECIES support:

SEC1: --enable-eccencrypt=yes
ISO 18033: --enable-eccencrypt=iso18033
wolfSSL proprietary version: --enable-eccencrypt=old

ECIES Features:

Encryption: AES CBC or Counter
Integrity: HMAC-SHA2-256
Keys: ECDHE
Nonce: for each message to prevent replay
Authentication: Out of band

TLS v1.3 Example

TLS v1.3 Features:

Encryption: AES-GCM or ChaCha20/Poly1305
Authentication: Standard X.509 certificates against long term key (recommend ECC)
Resumption: Session Tickets.

BTLE Simulator

These example use a BTLE simulator to demonstrate communications between devices. The simulator uses IPC (pipes) to communicate between threads.
