This paper proposes a security framework for Internet of Things (IoT) based on blockchain. The solution provides the two features: (1) Access control for IoT devices, which allows users to pay a fee to the device’s owner to access the device for a certain period of time.

The term AAA has been traditionally used to refer to Authentication, Authorization, and Accounting activities. All of those activities are of crucial importance for the operation of an IP network, although typically they are not so visible to the end user. The importance of AAA functions lies in the fact that they provide the required protection and control in accessing a network. As a consequence, the administrator of the network can bill the end user for services used.

Frequently, the only protection for a URL is that links to that page are not presented to unauthorized users. However, a motivated, skilled, or just plain lucky attacker may be able to find and access these pages, invoke functions, and view data. Security by obscurity is not sufficient to protect sensitive functions and data in an application. Access control checks must be performed before a request to a sensitive function is granted, which ensures that the user is authorized to access that function....

It is becoming clearer every year that workstations require as much comprehensive IT security attention as servers – particularly as the popularity of mobile workstations (laptops) continues to rise. Microsoft has advanced several technologies in Windows Vista to increase workstation security. This white paper introduces eight such technologies: • User Account Control • IE7 Protected Mode • Service Hardening • Windows Resource Protection • Windows Defender • TPM and BitLocker • Network Access Protection • PatchGuard and Driver Signing (64-bit platform)...

Control of access to sensitive information is of concern to managers, information officers, DBAs, and application developers, among many others. Selective access control based on a user's level of security clearance can ensure confidentiality without overbroad limitations. This level of access control enables confidence that sensitive information will be unavailable to unauthorized persons even while general users have access to needed information, sometimes in the same tables.
