“…Mobile platforms such as Android and iOS use several techniques to protect the integrity of the operating systems, isolate individual applications [18] and protect the data stored [19] on the device. Several papers assess [20] the security mechanisms included in these platforms or present additional mechanisms to further increase the security of the platform.…”

Manufacturing processes are currently visualised and controlled using dedicated Human Machine Interface (HMI) components. These single-use devices are typically located at fixed locations in the production hall. This poses significant constraints regarding mobility and extensibility. Smartphones can provide an interesting complementary HMI solution to those standard HMI components. Smartphones provide a mobile solution which allows engineers to access production process data (e.g. access sensor values or PLC logs) from anywhere in the field. Moreover, software on smartphones can be easily extended to provide additional functionality such as access to company services, resources on the Internet or interaction with IoT devices installed in the industrial network. This paper presents the design of a mobile extensible HMI using the Android platform. The design focuses on tackling the security requirements associated with smartphone access to the industrial control system network. The design relies on the Android for Work framework contained in the Android 5+ platform. A prototype setup is realized, illustrating the feasibility of the proposed solution.

“…For storage encryption, the acceptable runtime is higher and may extend slightly higher than 1000ms. But note that the parameters used for scrypt in Android since version 4.4 [11] for storage encryption (namely (N, r, p) = (2 15 , 3, 1) [34]) yields moderate running times (around 100ms on server CPUs, but higher on typical mobile devices).…”

“…For remote server login he proposes N = 2 14 , r = 8, p = 1, which uses 16 MB. Android since version 4.4 uses scrypt for storage encryption[11], with parameters (N, r, p) = (2 15 , 3, 1)[34].…”

Technology and Practice of Passwords

Passwords are still by far the most widely used form of user authentication, for applications ranging from online banking or corporate network access to storage encryption. Password guessing thus poses a serious threat for a multitude of applications. Modern password hashes are specically designed to slow down guessing attacks. However, having exact measures for the rate of password guessing against determined attackers is non-trivial but important for evaluating the security for many systems. Moreover, such information may be valuable for designing new password hashes, such as in the ongoing password hashing competition (PHC).In this work, we investigate two popular password hashes, bcrypt and scrypt, with respect to implementations on non-standard computing platforms. Both functions were specically designed to only allow slow-rate password derivation and, thus, guessing rates. We develop a methodology for fairly comparing dierent implementations of password hashes, and apply this methodology to our own implementation of scrypt on GPUs, as well as existing implementations of bcrypt and scrypt on GPUs and FPGAs.

“…Researchers propose a generic architecture for providing security services in the cloud for smartphones within a corporate environment. P. Teufl et al [13] researched that high usability of smartphones and tablets by consumers as well as the corporate and public sector. The researchers proposed different encryption systems for android's that are assessed and their susceptibility to different attacks is analyzed in detail.…”

Cloud computing is providing resources advent over a network which is benefiting almost all IT services. With software as a service and storage as service more and more enterprise applications are shifting towards Cloud platform making Smartphones their thin Clients and thus promoting Mobile Cloud Computing. Mobile cloud computing is a computing of data and storage of data outside the mobile device. The data storage and data processing happens on the cloud not on the mobile device. Thus mobile cloud computing provides the use of technology smartly and reserving the scarce resources of mobile. But as more and more sensitive information is passing the Mobile phones, the need of securing the information and creating a trust between the Mobile user and the Storage Cloud is emerging. This leads to the area to be focused that is security of mobile data, offloading to cloud for storage and processing. There are many encryption techniques used by researchers such as RSA, DES and AES for security purpose. These techniques have some loopholes. So, we are proposing a framework which will use ECC technique with progressive encryption to provide better security to the mobile data on cloud without creating much overhead on the Smartphone.
