Although many studies proved that it was possible to embed application servers on a chip with limited resources, security considerations were generally marginalized. Due to their frontal position, application servers are subject to an increasing number of threats. These vulnerabilities are actually ignored in most cases mainly because of cost constraints. This paper introduces the concept of Secure...
One of the most efficient methods for cracking passwords, which are hashed based on different cryptographic algorithms, is the one based on “Rainbow Tables”. Those lookup tables offer an almost optimal time-memory tradeoff in the process of recovering the plaintext password from a password hash, generated by a cryptographic hash function. In this paper, the first known such generic system is demonstrated...
Field-programmable gate arrays provide a flexible and easy-to-configure implementation platform that supports the development of tamper-proof networked embedded systems. Many of these systems employ the Advanced Encryption Standard algorithm in order to achieve a secure mode of operation. Since this algorithm is of a high computational complexity, this paper utilizes various hardware-software co-design...
This paper presents principles and results of dynamic testing of an SRAM-based FPGA using time- resolved fault injection with a pulsed laser. The synchronization setup and experimental procedure are detailed. Fault injection results obtained with a DES crypto-core application implemented on a Xilinx Virtex II are discussed.
