Latest Patents

Zbigniew Chamski holds a patent for "Code flow protection with error propagation." This invention provides an execution system that includes a central processing unit (CPU) and a system memory (SM) that stores a genuine program (cGC) with ciphered instructions (Cl) at determined addresses. A secure agent component (SAC) is dedicated to protecting the execution of the cGC. The SAC features a signature register (SR) that stores an instruction flow signature based on previously executed instructions, along with a ciphering/deciphering module. A new instruction flow signature is determined based on the current instruction and the previous instruction's flow signature before being stored in the signature register (SR). This innovative approach enhances the security and integrity of program execution.
