Abstract
Security of accessing cloud services is very crucial problem for front-end devices in network. In the research literature, the typical methods aim for certificates and key mutual authentication of devices. However, in this paper, we propose a new efficient design scheme, the key idea of the scheme is to adopt the elliptic curve cryptography (ECC) algorithm for authentication, combined with attributes information of front-end device using smart card, and use the high security Advanced Encryption Standard (AES) algorithm to encrypt data instead of the conventional DES and 3DES algorithms. Especially, in the process of data transmission, the authentication server regularly detects the legitimacy identifier of access devices and synchronously update the share key of session to resist the key hijacking crack. Thus, the front-end device with the secure modular of smart card not only becomes trusted, but also the device’s information and data are well protected in the accessing cloud network.
