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...
Trusted computing platforms aim to provide trust in computations performed by sensitive applications. Verifying the integrity of memory contents is a crucial security service that these platforms must provide since an adversary able to corrupt the memory space can affect the computations performed by the platform. After a description of the active attacks that threaten memory integrity, this paper...
Physically Unclonable Functions (PUFs) are emerging cryptographic primitives used to implement low-cost device authentication and secure secret key generation. Weak PUFs (i.e., devices able to generate a single signature or to deal with a limited number of challenges) and Strong PUFs (i.e., devices able to deal with multiple challenges) are widely discussed in literature. The most investigated solutions...
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...
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...
