  1. An improved signature scheme with subliminal channel

    一種改進的具有潛通道的簽名
  2. A subliminal channel is a covert communication channel to send a message to an authorized receiver. this channel is constructed in the output crypto - data of an applied public - key cryptosystem such as digital signature, authentication, and so on. the message can not be discovered by any unauthorized receivers

    閾下通道是指在基於公鑰密碼技術的數字簽名、認證等應用密碼體制的輸出密碼數據中建立起來的一種隱蔽通道，除指定的接收者外，任何其他人均不知道密碼數據中是否有閾下消息存在。
  3. A general model of subliminal channels and some necessary conditions that the carrier cryptosystem must holds are given. a secret channel and an attack channel are first defined and some basic conclusions of the security are given. two new parameters, the embedding rate and the channel - using rate, that have large effects on the capacity and the security of subliminal channels are first defined

    給出了閾下通道系統的一般模型和宿主密碼系統須滿足的必要條件，首次定義了閾下通道中的秘密通道與攻擊通道，並給出關于安全性的基本結論，首次定義了對容量和安全性有一定影響的嵌入成功率和通道使用率兩個新參數。
  4. The capacity of subliminal channels in elgamal signatures is studied. the capacity of broadband channel and the optimal schemes in 18 general elgamal signatures are analyzed. the relation between the capacity and the embedding rate of narrowband subliminal channels based on the exhausting search is studied

    給出了容量的定義，理論上界以及影響容量的幾個因素，給出了嵌入成功率和通道使用率對容量的影響，研究了elgamal簽名中寬帶通道的容量，分析了18種廣義elgamal簽名中的寬帶閾下通道的容量並指出了最優方案，具體研究了基於搜索的窄帶通道的容量與嵌入成功率的關系，具體研究了牛頓通道的帶寬。
  5. The schemes to avoid the subliminal channels are summarized and compared with each other. a conclusion is drawn that the subliminal channel introduced by the semantic randomness of the input harmless message of cryptosystem can not be completely avoided. a new scheme to generate elgamal - type signatures that are free of any subliminal channels introduced by its session key is designed

    總結了封閉閾下通道的若干方法並對各方案優缺點進行了對比分析，給出了作為系統輸入的無害消息的語義隨機性不可能完全封閉的結論，設計了新的對elgamal類簽名中會話密鑰進行完全封閉的方案，討論了現有封閉方案的實用性。
