We consider the problem of post-quantum secure and ultra-reliable\ncommunication through a heterogeneous network consisting of multiple\nconnections. Three performance metrics are considered: security, throughput,\nand in-order delivery delay. In this setting, previous work has looked,\nindividually, at the trade-offs between in-order delivery delay and throughput,\nand between security and throughput. This is the first work considering the\ntrade-off between all three for heterogeneous communication networks, while\ntaking the computational complexity into account. We present LL-HUNCC, a low\nlatency hybrid universal network coding cryptosystem. LL-HUNCC is an efficient\ncoding scheme which allows for secure communications over a noisy untrusted\nheterogeneous network by encrypting only a small part of the information being\nsent. This scheme provides post-quantum security with high throughput and low\nin-order delivery delay guarantees. We evaluate LL-HUNCC via simulations on a\nsetting inspired by a practical scenario for heterogeneous communications\ninvolving a satellite communication link and a 5G communication network. Under\nthis scenario, we compare LL-HUNCC to the state-of-the-art where all\ncommunication paths are encrypted via a post-quantum public-key cryptosystem.\n
