摘要

探讨了小区广播系统在量子计算时代面临的安全挑战，并提出基于后量子密码（post-quantum cryptography，PQC）算法的安全增强方案。首先，分析小区广播系统及其安全架构，识别其在量子计算环境下的潜在脆弱性；其次，评估主流PQC数字签名算法的安全性与性能特性，设计纯后量子证书、混合证书及组合证书3类后量子数字证书结构，并提出适配现有系统的密钥管理机制、消息发送流程及消息格式扩展方案；最后，从计算开销、存储占用及消息长度适配性等方面进行实验验证。结果表明，所提方案具备部署可行性，可为小区广播系统向后量子安全体系的演进提供技术参考与实现路径。

Abstract

A security enhancement scheme based on post-quantum cryptography (PQC) was presented to address the security threats posed to cell broadcast systems in the quantum computing era. Firstly

the cell broadcast system and its security architecture were analyzed to identify potential vulnerabilities in a quantum computing environment. Subsequently

mainstream PQC digital signature algorithms were evaluated in terms of their security and performance characteristics. Three types of post-quantum digital certificate structures—pure post-quantum certificates

hybrid certificates

and composite certificates—were designed

and a key management mechanism

message transmission process

and message format extension scheme compatible with existing systems were proposed. Finally

the proposed scheme was experimentally validated from perspectives such as computational overhead

storage occupancy

and message length adaptability. The results demonstrate the deployment feasibility of the scheme

indicating that it could provide technical reference and an implementation path for the evolution of cell broadcast systems toward a post-quantum security architecture.
