摘要： PROBLEM TO BE SOLVED: To obtain an encryption communication method for attaining encryption communication between terminals, and to provide a system. SOLUTION: The terminals register the key generating information in respectively different session management servers, which comprises a plurality of setting items required to determine a setting value for generating a usable key by own terminal and stores the candidate of the setting value in each setting item. When the encryption communication is established between the terminals, each session management server is linked with a key generating information management server, and the key generating information management server selects an encryption algorithm suite, based on the key-generating information. The session management server for generating parameters, based on the selected algorithm suite, acquires the information concerning the selected algorithm suite from the key-generating information management server, generates the key to be used for the inter-terminal encryption communication, based on the information, and distributes the key to the respective terminals.

摘要： PROBLEM TO BE SOLVED: To solve the following problem in a conventional technology that it takes time for processing because negotiation of a security parameter is required prior to communication in order to protect secrecy and integrity of an SIP message or, every time the SIP message is transmitted/received, using a public key cryptography is necessary for encryption processing, decryption processing, electronic signature processing, and electronic signature verification processing. SOLUTION: When messages are transmitted/received between two entities such as an SIP server and an SIP client, in the case shared information for encryption is shared between the entities, encryption is carried out by the shared information and, on the other hand, in the case the shared information for encryption is not shared, encryption is carried out by the public key of the destination entity. In the communication after the encrypted data, the encrypted message includes shared information to be used when the destination entity of the encrypted data encrypts or decrypts messages.

摘要： PROBLEM TO BE SOLVED: To reduce the possibility of flowing out of personal information in the case of user authentication of an information terminal. SOLUTION: A management device 20 has a user certificate DB for registering a user certificate associated with a certificate number. The management device 20 reads the user certificate associated with the certificate number given from a service providing device 10 from the user certificate DB, decides whether this satisfies a prescribed Web browsing condition or not, and decides the propriety of Web browsing. Then, propriety information indicating the decided content is given to the service providing device 10, which acquires the certificate number from the information terminal 40, informs the management device 20 of this and acquires the priority information from the management device 20. Then, only when the acquired propriety information indicates permission of blowsing, the information terminal 40 is permitted to browse the Web.

摘要： PROBLEM TO BE SOLVED: To enable a first user to confirm that a second user receives electronic information when the electronic information is transmitted from the first user through a network to the second user. SOLUTION: A transmitter 210 generates the electronic information to be transmitted to a recipient 211 and transmits this electronic information and the destination of the recipient 211 to a distributor 212. The distributor 212 generates a cryptographic key at random, enciphers the received electronic information with this cryptographic key and generates a cryptographic sentence. Then, the cryptographic sentence is transmitted to the recipient 211. The recipient 211 generates a receipt showing the reception of the cryptographic sentence and returns the receipt to the distributor 212 later. The distributor 212 verifies the normality of the receipt and only when the receipt is confirmed normal, the cryptographic key is transmitted to the recipient 211. At the same time, the receipt is transmitted to the transmitter 210. The recipient 211 deciphers the cryptographic sentence with the received cryptographic key and restores the electronic information.
