Abstract: Due to the frequent data communication among activities in the processes and the loose coupling characteristics of the microservice architecture,the business process management systems based on microservice architecture generally have the communication security problems such as man-in-the-middle attacks.For this problem,Therefore,a hybrid encryption data communication method based on microservice architecture was proposed to support reliable execution of business processes.An additional third-party asymmetric encryption service was constructed,and the security of transmission key in the hybrid encryption algorithm was ensured through the two stages of generating digital signatures and verifying public keys.The unmodifiable and non-repudiation of the data communication was guaranteed with the key of secure transmission.The communication efficiency of the proposed secure communication method and the traditional hybrid encryption communication method were compared by experiment,and the result showed that the proposed method had the good communication efficiency under the premise of ensuring communication security and could support the reliable execution of business process.
