Common Randomness and Secret Key Capacities of Two-Way Channels [PDF]
, 2011 Common Randomness Generation (CRG) and Secret Key Establishment (SKE) are fundamental primitives in information theory and cryptography. We study these two problems over the two-way communication channel model, introduced by Shannon. In this model, the common randomness (CK) capacity is defined as the maximum number of random bits per channel use that ...

Fault-tolerant secret key generation
, 2012 Mobile nodes observing correlated data communicate using an insecure bidirectional switch to generate a secret key, which must remain concealed from the switch. We are interested in fault-tolerant secret key rates, i.e., the rates of secret key generated

Secret-Key Generation Using Correlated Sources and Channels [PDF]
, 2011 We study the secret-key capacity in a joint source-channel coding setup-the terminals are connected over a discrete memoryless channel and have access to side information, modelled as a pair of discrete memoryless source sequences. As our main result, we

Drop of the secret key capacity by the multiple spot eavesdropping in wireless secret key agreement based on the complex channel coefficient [PDF]
, 2022 無線物理層セキュリティの一種として電波伝搬特性に基づく秘密鍵共有が注目されている．しかし，複数地点盗聴に対する秘密鍵容量の低下に関する検討が少ない．本論文は、複素チャネル係数に基づく秘密鍵共有において秘密鍵容量の理論式を導出した．また，複数地点盗聴に対する漏洩情報量の理論式を導出し、盗聴地点数の増加とともに漏洩情報量の増加することを示した．また、理論式の妥当性をシミュレーションにより確認した．次に，単調な伝搬環境におけるチャネル係数の空間相関係数の試算を行い ...

Large-capacity three-party quantum digital secret sharing using three particular matrices coding
, 2016 In this paper, we develop a large-capacity quantum digital secret sharing (QDSS) scheme, combined the Fibonacci- and Lucas-valued orbital angular momentum (OAM) entanglement with the recursive Fibonacci and Lucas matrices.
