Disclosed is a method for creating and verifying SOAP messages in web service security using signature encryption. The SOAP message sender encrypts a signature used for SOAP message security with a secret key for encrypting data to be contained in the SOAP body. The encrypted signature is inserted in the security header of the SOAP header and sent to the recipient. The SOAP message recipient decrypts the encrypted key with his/her private key and restores the secret key. The restored secret key is used to decrypt the encrypted signature in the security header of the SOAP header, and the decrypted signature is used to verify the SOAP message.

The apparatus for measuring the performance of embedded devices includes: a transceiver that transmits and receives data to and from the embedded devices; an interrupt generator that generates interrupt signal; a controller that controls the interrupt generator and the transceiver to generate the interrupt signal and transmits them to the embedded devices and performs a control to calculate real-time performance when the response signal to the interrupt signal are received from the embedded device through the transceiver; and a calculator that calculates the real-time performance of the embedded devices based on the interrupt signal generating time and the response signal receiving time.

An ontology-based ad hoc service discovery system includes a local service cache, a cache manager, a service description unit, a query processor, a service semantic inference unit and a node daemon. The local service cache restores a service ontology by collecting class information of all services advertised on an ad hoc network and stores the service ontology. The cache manager manages the local service cache and performs various preset operations on the cache. The service description unit stores a description of a corresponding service for use in initializing the local service cache. The query processor starts performing a semantic based service query protocol by receiving a service query from a user or an application program. The service semantic inference unit inspects whether the service query transmitted from a client is coincident with the content of the service. The node daemon performs a service cache synchronization protocol with neighboring nodes.
