With the advent of the Internet of Things (IoT), electronics devices are everywhere in our lives. This omnipresence implies a growing of security issues (data or identity theft, hostile takeover of sensitive equipments…). To counter security vulnerabilities, “Security by Design” methods are being developed. It advises to think about security from the beginning of the conception at both software and...
The bus between the System on Chip (SoC) and the external memory is one of the weakest points of computer systems: an adversary can easily probe this bus in order to read private data (data confidentiality concern) or to inject data (data integrity concern). The conventional way to protect data against such attacks and to ensure data confidentiality and integrity is to implement two dedicated engines:...
Nowadays, cryptography is widely used in many different devices (smartphones, tablets, computers, etc.). One of the most used cryptographic algorithms is AES (Advanced Encryption Standard). Crocus Technology is developing a technology called Match-In-Place TM (MIP). This is a memory based on comparison function. With this technology, data stored in the memory can be compared to an input data. The...
Electro-Magnetic Analysis has been identified as an efficient technique to retrieve the secret key of cryptographic algorithms. Although similar mathematically speaking, Power or Electro-Magnetic Analysis have different advantages in practice. Among the advantages of EM Analysis, the feasibility of attacking limited and bounded area of integrated systems is the key one. Within this context, the contribution...
Nowadays, there are lot of applications where remote update is an essential service. Indeed, in high volume sale products or space-based systems it is too expensive to retrieve the device in order to update it. Field Programmable Gate Arrays (FPGAs) are able to perform that with success through a network. However, this feature may give rise to security flaw like spoofing and replay attacks. These...
