Abstract: A key exchange system according to an embodiment includes: a plurality of terminals that perform key exchange; and a server that performs authentication of each of the terminals and mediation of the key exchange, in which the server includes a nonce generation unit that generates a nonce used when the authentication is performed between the server and the terminal by federation using OpenID Connect, a key generation unit that generates a public key and a secret key of token control encryption, a first transmission unit that transmits the nonce and the public key to the terminal, and a decryption unit that decrypts a ciphertext received from the terminal by using the secret key and a token received from the terminal, and the terminal includes an encryption unit that generates a ciphertext obtained by encrypting predetermined data by using the public key and a token generated from the nonce, a second transmission unit that transmits the ciphertext to the server, and a long-term secret string generation unit tha

Abstract: A powdered wheat protein that can achieve both a high dough-formation speed and a high bulk density is obtained by drying a pasty raw material formed by kneading a wheat protein, an acid, and water, by flash drying or freeze drying.

Abstract: Provided with a weight release device capable of being operated in deep sea same as the conventional weight release device without accompanying a mechanical operation at all to avoid troubles of mechanical operation occurred in the conventional weight release device. The weight release device includes a housing fixed to the underwater observation device; a thread made of thermoplastic resin; electric heater portions; a weight support plate; a locking member of the thread made of the thermoplastic resin; and a ring for hanging the weight. The thread made of the thermoplastic resin is arranged from a start point housed in the housing, arranged to pass through the first electric heater portion, locked to the locking member of the thread made of the thermoplastic resin, arranged to pass through the second electric heater portion housed in the housing, and returned to an end point housed in the housing. The ring for hanging the weight is fixed to a lower surface of the weight support plate.

Abstract: A segment identifier (SID) manager interfaces with clients by way of a library. Clients implementing network services and needing SIDs according to internet SRv6, are allocated blocks by the SID manager using the library. Clients assign SIDs from the block independent of the SID manager using the library. Where a threshold portion of the block is assigned, the library requests an additional block of SIDs from the SID manager. Clients transmit context mappings of assigned SIDs to the SID manager for use by administrators and to enable recovery in the event of failure.

Abstract: A cellular data communication network includes a gNodeB connected to a UPF by an IP network. A first translation module translates GFP packets into IP packets transmitted over the IP network. A second translation module translates the IP packets back into IP packets and forwards the IP packets to the UPF. A PFCP proxy snoops information and provides it to a BGP module that programs the translation modules and a routing module to perform routing of packets in bypass of the UPF. The BGP module may program the first translation module with an SR policy associated with a binding SID that is bound to an interface to the gNodeB. The SR policy may invoke translation according to a function. The routing module may be programmed to embed GTP information in an SRH header that is used by the first translation module. BGP module may also distribute routing and VPN updates.

Abstract: A cellular data communication network includes a BBU connected to a UPF by an IP network. A first translation module translates GFP packets into IP packets transmitted over the IP network. A second translation module translates the IP packets back into IP packets and forwards the IP packets to the UPF. A PFCP proxy intercepts control packets of the UPF. Information snooped by the PFCP proxy is provided to a routing/SDN controller that programs the translation modules and a routing module to perform routing of packets in bypass of the UPF.

Abstract: Disaggregated border gateway protocol (BGP) enables an eBGP session between an internal node an external node to continue despite failover of a perimeter through which the eBGP session is established. eBGP control traffic is trapped by a perimeter router and forwarded to a BGP speaker on the internal node through an IP tunnel. Failover is detected in response to a change in a source address of the IP tunnel over which eBGP control traffic is received. The BGP speaker announces routes to the external node that include a reference to an internal address of an active perimeter router. In response to failover, the BGP speaker announces updated routes referencing the standby router for the perimeter router.

Abstract: Importing of a UE address into a VRF of perimeter equipment is facilitate by receiving a VPN update from the perimeter equipment including a route target of the perimeter equipment and a gNodeB address. In addition, session information is obtained by intercepting traffic between the UE address and a UPF. The session information including the UE address and address of a gNodeB to which the UE is connected. By matching the gNodeB addresses from the VPN update and the session information, the route target of the perimeter equipment to which the UE is connected may be determined. The UE address may then be imported exclusively into the VRF of the perimeter equipment.
