Identity-Based Encryption (IBE) is considered an alternative to traditional certificate-based public key cryptography to reduce communication overheads in wireless sensor networks. In this work, we build on the well-known latticebased DLP-IBE scheme to construct an ID-based certificateless authenticated key exchange for post-quantum Transport Layer Security (TLS) handshakes. We also propose concrete parameters for the underlying lattice computations and provide detailed implementation results.
