一种名为通过回波加密探测进行秘密消息传输（STEEP）的安全通信传输方案，在用户有足够非对称功率分配时，即使窃听信道比用户间信道强得多，也能实现正保密率。本文考虑将STEEP应用于多天线用户与多天线窃听者之间的MIMO（或MIMOME）信道的优化问题。首次揭示了使用优化预编码器可显著提高MIMO STEEP的可达保密率。
英文摘要
A transmission scheme for secure communications, called secret-message transmission by echoing encrypted probes (STEEP), can deliver a positive secrecy rate, even when eavesdropping channels are much stronger than that between users, subject to sufficient asymmetric power allocations from users. This paper considers an optimization problem for STEEP applied to MIMO (or MIMOME) channels between multi-antenna users and multi-antenna Eve. We reveal for the first time a significant increase of the achievable secrecy rate of MIMO STEEP using optimized precoders.
