AI Technical Summary

Technical Problem

The existing EPC coding has security deficiencies, making it difficult to ensure the security of sensitive information. Traditional encryption algorithms cannot provide high-strength encryption protection while retaining the coding format, affecting the information interaction and operational efficiency of military and civilian aviation equipment.

Method used

The aircraft equipment code is converted into the EPC code standard format, and an improved Feistel network is used for format-preserving encryption. By splitting the EPC code into a scrambling code, a left half, and a right half, a pseudo-random sequence is generated for iterative encryption to ensure that the code format remains unchanged and improve security.

Benefits of technology

It achieves the goal of improving information security and simplifying code conversion while retaining the EPC coding standard format, optimizing the operational efficiency and information traceability of military and civilian aviation equipment, and providing higher security protection.

Abstract

The present invention relates to the field of coding, and more particularly to an improved Festel-based encryption method for EPC codes of aircraft equipment. The method comprises the following steps: S1, mapping the aircraft equipment code to the EPC code; S2, encrypting the aircraft equipment EPC code using the improved Festel network, including the following substeps: S21, segmenting the EPC code into scrambling, left, and right halves; S22, generating a pseudorandom sequence using a pseudorandom number generator; S23, obtaining a binary number as a round key based on the pseudorandom sequence; and S24, iterative encryption to obtain a final encrypted result. The present invention maps traditional aircraft equipment codes to EPC codes and encrypts them using the improved Feistel network. This method not only enhances information uniformity and traceability, but also ensures data security while preserving the standard format of the EPC code.
