Latest Patents
One of Lange's latest patents focuses on the use of hashing in a secure boot loader. This innovation involves machine instructions that comprise a bootstrap code, which are embedded within a critical component of an electronic game console. These instructions are designed to be inaccessible or unmodifiable. The preloader portion in a read-only memory (ROM) is hashed by the bootstrap code, and the resulting hash is compared to an expected hash value maintained within the bootstrap code. Further verification of the boot-up process is conducted by the preloader, which hashes the code in ROM to generate a hash value for the code. This value is then verified against a digital signature that defines the expected value for this hash. If any expected result is not obtained, the boot-up process is terminated. This technique ensures that the code used for booting the device remains unaltered and secure.
