Mainstream FPGAs and programmable SoCs employ different countermeasures during configuration and runtime to mitigate physical attacks. However, it has been demonstrated that sophisticated active attack techniques, such as laser voltage probing, can still bypass the bitstream protections during the configuration phase. On the other hand, although the security monitoring IP cores provided by FPGA vendors...
This paper describes the first attack utilizing the photonic side channel against a public-key crypto-system. We evaluated three common implementations of RSA modular exponentiation, all using the Karatsuba multiplication method. We discovered that the key length had marginal impact on resilience to the attack: attacking a 2048-bit key required only 9% more decryption attempts than a 1024-bit key...
Measuring instruments tend to be powerful devices, that have adopted general-purpose operating systems to offer the user a broader functionality that is not necessarily restricted towards measurement alone. In this paper, a flexible software system architecture that can be constructed out of freely available open source software is presented which addresses these challenges within the framework of...
We propose and implement an innovative remote attestation framework called DR@FT for efficiently measuring a target system based on an information flow-based integrity model. With this model, the high integrity processes of a system are first measured and verified, and these processes are then protected from accesses initiated by low integrity processes. Toward dynamic systems with frequently changed...
