    摘要： A method for establishing shared information is described. The method includes estimating characteristics of a communication channel between two nodes based on signals transmitted between the nodes. The method also includes transmitting a signal from the first node to the second node, the signal being modulated with a first data sequence according to a first estimated characteristic, and transmitting a signal from the second node to the first node, the signal being modulated with a second data sequence according to a second estimated characteristic. Shared information is formed at each of the first and second nodes based on at least a portion of the first data sequence and at least a portion of the second data sequence.

    摘要： An inventive wireless communication apparatus that, in a wireless communication system to which a secret key scheme is applied, can generate a secret key, which is different from a secret key generated by a third party, even if a wireless signal is intercepted by the third part having an approximate propagation path environment to a receiving wireless communication apparatus. In the inventive apparatus, an eigenvalue selecting part (317) of a secret key generating part (207) selects a maximum one of MIMO channel eigenvalues received from an eigenvalue detecting part (206) and inputs the selected maximum eigenvalue to a quantizing part (327). The quantizing part (327) quantizes the magnitude of the maximum eigenvalue received from the eigenvalue selecting part (317) to produce and input a quantized data to a key generating part (337). The key generating part (337) uses a predetermined scheme to generate a secret key from the quantized data received from the quantizing part (327), and inputs the generated secret key to a control part or the like not shown.

    摘要： There is disclosed a radio communication device capable of preventing wire-tap of an encrypted communication even if a radio signal is wire-tapped by a third person in a radio communication system using the MIMO technique. In this device, an inter-channel correlation calculation unit (104) calculates an inter-channel correlation value between two channels in the MIMO channel according to four channel estimation values inputted from a channel estimation unit (103). The six channel correlation values calculated are all inputted to a channel selection unit (105). The channel selection unit (105) selects a minimum channel correlation value from the six channel correlation values inputted from the inter-channel correlation calculation unit (104) and reports two channels corresponding to the selected channel correlation value to an inter-channel correlation monitoring unit (110) and inputs the channel estimation value of the two channels to a secret key generation unit (106).

    摘要： A cryptographic communications system enables two entities related by an insecure communication channel and having initially no privately shared knowledge, to agree on a shared unconditionally secure information. Each one of the entities has the capability to generate a new form of randomness called Deep Random, such that any other entity than itself cannot know anything about the probability distribution except a given public characteristic. The internal system of each entity is made up with: (1) a Deep Random Generator (DRG) capable of generating Deep Random signals and of making calculations using the generated signals, and (2) an Interactive Communication Module (ICM) capable of publishing to and reading from the insecure channel. The two entities execute a communication protocol such that they can each compute their respective estimations of the shared information that are probabilistically as close as desired from perfect equality.
