Cumulative Attestation Kernels for Embedded Systems

Formal Verification of Embedded Systems for Remote Attestation

Embedded systems are increasingly pervasive, interdependent and in many cases critical to our every day life and safety. As such devices are more and more subject to attacks, new protection mechanisms are needed to provide the required resilience and dependency at low cost. Remote attestation (RA) is a software-hardware mechanism that securely checks the internal state of remote embedded device...

Using Software-based Attestation for Verifying Embedded Systems in Cars

With advances in automobile electronics, we find a rapid proliferation of embedded systems in cars, both in safety-critical applications and for passenger comfort. These embedded systems are increasingly networked for their operation and enhanced functionality. However, the increased connectivity of embedded systems also greatly complicates design, increases the number of failure modes, and int...

A Direct Anonymous Attestation Scheme for Embedded Devices

Direct anonymous attestation (DAA) is an anonymous authentication scheme adopted by the Trusted Computing Group in its specifications for trusted computing platforms. This paper presents an efficient construction that implements all anonymous authentication features specified in DAA, including authentication with total anonymity, authentication with variable anonymity, and rogue TPM tagging. Th...

How to Use Real-Time Multitasking Kernels in Embedded Systems

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
