Abstract—Smartwork is a flexible type of work that provides users with a more convenient work possibility, which refers to employees who work away from the company’s office in any capacity. Smartwork technologies often need additional protection because their nature generally places them at higher exposure to external threats. Therefore, smartwork application should provide securing infrastructures for both of users, inside and outside of the organization. This paper proposes a NFC based privacy preserving user authentication scheme as a basic security building block for smartwork environment, which is focused only on the mobile office one of smartwork environment. The proposed scheme provides anonymity and untraceability, which requires for the ubiquitous environment applications. The proposed scheme could be used as a basic building block for security on the various smartwork environments.

Index Terms—Smartwork, NFC, authentication, privacy, security, mobile office.
