In this study, we investigated the efficiency and the security of information theoretic cryptography, and main results are summarized as follows. First, in the quantum key distribution protocols, we clarified the optimal polarization axis compensation method for the unital channel class. Second, we clarified that the key generation method widely used in literatures is not secure in the sense of the so-called strong security criterion. Third, in the secret key agreement from correlated Gaussian sources, we clarified the trade-off between the public communication rate and the key generation rate.

本文研究了信息论密码体制的效率和安全性，主要结果如下。首先，在量子密钥分配协议中，明确了单位信道类的最优偏振轴补偿方法。其次，我们澄清了文献中广泛使用的密钥生成方法在所谓的强安全准则意义下是不安全的。第三，在相关高斯源的密钥协商中，我们阐明了公开通信速率和密钥生成速率之间的权衡。
