摘要： PROBLEM TO BE SOLVED: To suitably perform safe communication over a network. SOLUTION: A security gateway (SG) 2 at the start side blocks communication from a host 1, retrieval is made to find a security gateway (SG) 5 at the answer side using a destination side address (address of a host 4) of the communication as a key, and, if the gateway (SG) 5 at the answer side is found from the retrieval result, a security policy (SP) is set for executing an IPsec tunnel mode between the security gateways (SG) 2, 5. Then an IKE program is started on the security gateways (SG) 2, 5, and, after setting security association (SA), the security gateway (SG) 2 at the start side unblocks the communication from the host 1 to the host 4 to perform communication between the hosts 1, 4.

摘要： PROBLEM TO BE SOLVED: To provide a data sharing method, a program and an apparatus which makes an apparatus having a high computation capacity compute without disclosing secret information, thereby finishing with a reduced quantity of computations to be executed by itself at a high security. SOLUTION: For sharing secret data y_AB with communication parties using the Diffie-Hellman public key distribution system, the data sharing method obtains data y_1st from data r_1st using commission computation, generates data y_A in a y_init*y_1st mod p, and sends the data y_A to the communication parties (steps S102, S106). And it obtains data y_AB from data r_init + r_1st, using commission computation (steps S107, S111) where y_init = g^(r_init) mod p. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method for setting a parameter for cryptocommunication which is intuitive, intelligible and highly reliable.
SOLUTION: This method for setting a parameter uses a device having a communication means provided with a terminal for performing connection by physical contact and a means for recording parameters such as identification information obtained by collecting the following data: cryptographic algorithm, authentication algorithm, a key and the identifier of the opposite communication party. The method comprises a step in which the device connected to one opposite communication party receives the parameters from the one communication party and records the parameters, a step for transmitting the parameters recorded by the device connected to the other opposite communication party to the other opposite communication party, and a step for using the transmitted parameters to perform communication between the one opposite communication party and the other opposite communication party and confirming that the parameters are correctly shared.

摘要： PROBLEM TO BE SOLVED: To provide a technique which can make analysis and alteration of a program more difficult. SOLUTION: An information processor determines object instructions used as an object for reprogramming to camouflage instructions within instructions contained in the program of a processing object, creates the camouflage instructions corresponding to the object instructions, creates restore instruction for restoring the created camouflage instructions to the corresponding object instructions, rewrites the object instructions contained in the program of the processing object by the created camouflage instructions, and adds the restore instruction to this program. Wherewith, the restore instruction refers to a memory in which an output value of the processing instruction contained in the program of the processing object is stored, specifies a location or the object instructions in this program of the object instructions based on the referred value concerned or the object instructions, and performs the restoration.

摘要： PROBLEM TO BE SOLVED: To solve a problem that it is convenient to perform original processing at high speed for communication between specific devices, such as communication between the devices of the same kind or between devices of specific combination, but there is an overhead of the communication since IPv6 is rules of a network layer and it is preferable to realize a function like a mutual authentication of devices on its host layer.
SOLUTION: A host 202 identifies an address of a communicating party and when the address of the communicating party contains a prescribed value (a prescribed production vender code, for example), an original protocol (authenticating processing with the communicating party, for example) is started. When a host 203 within a local link sends router solicitation in order to acquire information required for determining a site local address and a global address from a router, the host 203 receives this and decides whether an address of the host 202 contains the prescribed value or not.

摘要： PROBLEM TO BE SOLVED: To set an IPv6 address by a simple procedure which cannot easily specify relevance with hardware.
SOLUTION: In IPv6, a function for automatically setting a link local IP address is supplied. The IP address is composed of a network prefix and an interface identifier. When the interface identifier is generated, time information and a counter of clock pulse are read (step S102). An address comprising the interface identifier generated from the value is generated (S104). An overlap address detection procedure is performed with the interface identifier as a temporary link local address (S105 to S107). A peculiar address is set.
