Latest Patents

One of Porteboeuf's latest patents is titled "Secured Execution Context Data." This invention discloses a circuit designed to monitor the security of a processor. The circuit accesses a memory that stores execution context data of a software program executed by the processor. It determines one or more signatures from the execution context data and compares these signatures with predefined signatures to ensure the processor's security. The developments describe that context data can include control flow data, and a signature may consist of a hash value or a similarity signature. Additionally, the integrity of signatures can be verified using a secret key, which may be obtained randomly or through a physically unclonable function. The patent also outlines various controls and countermeasures to address potential cyber attacks.

Another notable patent is the "Protection System and Method," which involves a device for executing cryptographic operations on bit vectors. This device performs at least one arithmetic addition operation between two operands, each comprising a set of components corresponding to specific bit positions. The device includes elementary adders that execute bitwise additions and generate carry outputs. Furthermore, it applies a mask to operand components using a masking logical operation, with the mask being a random number.
