Security asynchronous web services based on service-oriented architecture

Aiming at the security problem of service-oriented architecture (SOA) for asynchronous calls to services, this work proposed a semantic model of asynchronous invoking for web services. The abstract definitions of same domain invoking, self invoking, different domains invoking and different domains callback were described. Also the asynchronous message host key authentication (AMHKA) security algorithm and the dependent invoking mode were presented. According to the performance of AMHKA security algorithm, an optimize security invoking arithmetic (OSIA) was discussed. The test results of the services of network port and timeslot invoking in mobile network showed that the system performance loss was 19.2% by AMHKA security algorithm and was enhanced 16.8% by OSIA algorithm. So the system with OSIA has high performance and high security.
