The present application relates to the
cross field of
chip burning and
information security encryption, and discloses a
chip security burning dynamic
encryption verification system and method. The
system is composed of seven core modules, and seven core technologies of PUF hardware unique binding, two-way challenge-response
authentication, streaming segmented chain
encryption, block-by-block real-time
verification, six-state
adaptive security state
machine, key life cycle management and control, and whole-process encryption log tracing are fused. The method is divided into three stages of preparation before burning, dynamic encryption real-time burning and post-burning, realizes one session one key, one
chip one binding, whole-process
ciphertext transmission and real-time
verification, and triggers hierarchical
processing and hardware fuse in
abnormality. The present application solves the problems of low security, verification
lag and
key management loss in traditional burning, greatly improves the security, production efficiency and compliance of burning, and is suitable for high-security chip production burning scenes such as automotive, industry and finance.
