Hello everyone, I am Yin Xinxing from Huawei company. I am glad to join the TLS WG.
For the DLTS 1.3 draft, I am interested and have some ideas to talk with you. DTLS has a lot of application scenarios in IOT fields, but currently, there is some difficulty when DTLS 1.2 is applied to IOT devices, especially the battery-constrained IOT devices. For example, when the IOT device wakes up from sleep mode, the NAT table may have expired. Then the IOT device has to establish a new DTLS session or at least launches a resume process with the server, the corresponding power consumption is too high for some power-constrained devices. How can DTLS renegotiation be avoided in order to save battery? I hope the contributors of DTLS 1.3 (or DTLS 1.2) can consider this problem and give a proper solution. Any comment or idea about this problem is welcome. Regards, Yin Xinxing
