Software security poses substantial risks to our society because software has become part of our life. Numerous techniques have been proposed to resolve or mitigate the impact of software security issues. Among them, software testing and analysis are two of the critical methods, which significantly benefit from the advancements in deep learning technologies. Due to the successful use of deep learning in software security, recently,researchers have explored the potential of using large language models(LLMs) in this area. In this paper, we systematically review the results focusing on LLMs in software security. We analyze the topics of fuzzing, unit test, program repair, bug reproduction, data-driven bug detection, and bug triage. We deconstruct these techniques into several stages and analyze how LLMs can be used in the stages. We also discuss the future directions of using LLMs in software security, including the future directions for the existing use of LLMs and extensions from conventional deep learning research.

Plasmon-induced hot energy in metal nanostructures holds great promise for photocatalytic organic conversions. However,maintaining the high-energy state of hot electrons within these structures remains challenging, even in hybrid metal-semiconductor heterojunctions. The rapid relaxation of hot electrons（mall metal chalcogenide semiconductor clusters（P2） with gold nanorods（AuNRs）, which exhibits high-efficiency extraction of hot electrons and photocatalytic application. The robust binding of P2 cluster, with its smaller volume and larger energy level splitting compared to large-sized quantum dots, not only significantly increases the yield of hot electrons but also enables their rapid extraction and sustains long-lived（> 2 ns） high-energy states. As a proof of concept, the composite photocatalyst achieves near-infrared-lightdriven C（sp3）–S cross-coupling reactions for the first time. This protocol effectively produces over 50 alkylthioethers from a wide scope range of non-active alkyl bromides and chlorides, aryl and alkyl thiols. This work provides a new strategy for highefficiency extraction of hot electrons within plasmonic metal nanostructures and paves the way for hot electron-driven photocatalytic organic transformations.
