This is in response to Application filed 01/19/26. Claims 1 – 20 are pending.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –

Response to Arguments
Applicant's arguments filed 01/19/26 have been fully considered but they are not persuasive.
Applicant argues on page 7 of his response that, Campagna fails to teach or suggest at least the following features of pending claim 1:
“…receiving cipher text of a to-be-updated program sent from a system side, wherein the cipher text of the to-be-updated program is generated by encrypting the to-be-updated program with a preset key; b) performing verification, according to a key pre-stored in the network power supply, on the cipher text of the to-be-updated program, to obtain a verification result…”.
Examiner disagrees. Campagna in discloses in [0015, cipher used for encryption as well as discloses an encrypt a data key, and a, ciphertext produced by the encryption includes an authentication tag usable to verify authenticity and integrity of the AAD.
Applicants’ plain language of claims discloses receiving cipher text, encrypting and utilizing a preset key for performing verification. This is clearly taught by prior art and Applicants claims or limitations doesn’t preclude any other interpretation of claims as presented.
