The computer systems security arms race between attackers and defenders has largely taken place in the domain of software systems, but as hardware complexity and design processes have evolved, novel and potent hardware-based security threats are now possible. This paper presents a hybrid hardware/software approach to defending against malicious hardware. We propose BlueChip, a defensive strateg...

Today, most smartphones feature different kinds of secure hardware, such as processor-based security extensions (e.g., TrustZone) and dedicated secure co-processors (e.g., SIM-cards or embedded secure elements). Unfortunately, secure hardware is almost never utilized by commercial third party apps, although their usage would drastically improve security of security critical apps. The reasons ar...

Universal mobile telecommunication system (UMTS) has specified security mechanisms with extra features compared to the security mechanisms of previous mobile communication systems (GSM, DECT). A hardware implementation of the UMTS security mechanism is presented in this paper. The proposed VLSI system supports the Authentication and Key Agreement procedure (AKA), the data confidentiality proced...

An Overview of Hardware Security Modules This paper intends to introduce the concept of a cryptographic hardware device. It will describe its functions, uses and implementations. It will explain some of the desirable features offered by hardware vendors, as well as examine some of the pitfalls, weaknesses, and disadvantages associated with these types of devices. It will summarize the FIPS 140 ...

When writing can change your life, when writing can enrich you by offering much money, why don't you try it? Are you still very confused of where getting the ideas? Do you still have no idea with what you are going to write? Now, you will need reading. A good writer is a good reader at once. You can define how you write depending on what books to read. This towards hardware intrinsic security f...

Embedded hardware security has been an increasingly important need for many modern general and specific purposes electronic systems. Minute security algorithms with their expected low-cost and high-speed corresponding hardware realizations are of particular interest to fields such as mobile telecommunications, handheld computing devices, etc. In this paper, we analyze and evaluate the developme...
