Provided is a communication device. The communication device may transmit information to an external device using a terminal that makes a physical contact with the external device, and may sense the physical contact. In response to the sensed physical contact, the communication device may generate a link key.

A mobile system, a service system, and a service providing method for securely transmitting private information for use in a service are provided. The mobile system maintains at least one user data and identification data with respect to the user data used for processing at least one service, sets a session key for the service system, and encrypts service data identified based on the identification data to transmit to the service system.

Provided are a load balancing apparatus, which is configured to prevent an overload from occurring and perform effectively a load balancing operation even for servers distributed throughout a network, and a load balancing method performed using the same. the method may include determining whether a data packet received from a client may be a packet requiring a load balancing operation, determining at least one of physical servers provided in a distributed server farm as an target server to provide a service to the client, depending on the judgment, determining a forwarding path between the client and the target server, determining a header rewriting node, and referring the forwarding path and the header rewriting node to determine a forwarding rule and load the forwarding rule on a switch provided on the forwarding path.
摘要:
A mobile system, a service system, and a key authentication method to manage a key in a local wireless communication are provided. The mobile system and the service system may generate a hash value with respect to a public key of the service system using an identical hash function, and output a result corresponding to the hash value.

A distributed Rivest Shamir Adleman (RSA) signature generation method in an ad-hoc network and a node of an ad-hoc network. The distributed RSA signature generation method in an ad-hoc network includes distributing key share information, which is generated using a maximum distance separable (MDS) code and a random symmetric matrix, to a plurality of nodes; generating, in a fewer number of nodes than the plurality of nodes, a partial signature using the distributed key share information; transmitting the partial signature to a signature generation node; and generating an RSA signature using the partial signature, in the signature generation node.
