摘要：Security and its subcategory authentication are among the important subjects of cloud computing. In thissystem, user authentication mechanisms are carried out before providing access to resources. It isnoteworthy that this input gate is actually the pathway of many attacks. Therefore, designing a secure userauthentication mechanism significantly contributes to the overall security of the system. This process blocksattacks where the objective is to authenticate a user and when the user requests for cloud computingservices. As a result, this article aimed to introduce a new security solution for cloud computingenvironments through employing the EAP-TTLS protocol, replacing the common Data EncryptionAlgorithm (DEA) with a new one, and adding a digital signature to the authentication process. Afterimplementation of the proposed method in matlab, its performance was evaluated with RSA and ECDSAalgorithms. The results of simulation showed the improvement of performance in terms of memory usage,authentication time, and verification delay. The proposed method [digital signature], along with usernameand password, is used to improve security in user authentication process.
