human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "a survey on honeypot software and data analysis"
  Abstract: In this survey, we give an extensive overview on honeypots. This includes not only honeypot software but also methodologies to analyse honeypot data.

Connected through hyperedge HE-1 (induced by source paper "a first step towards understanding real world attacks on iot devices"):
  with members:
    - "siphon towards scalable high interaction physical honeypots"

Connected through hyperedge HE-2 (induced by source paper "from cyber security deception to manipulation and gratification through gamification"):
  with members:
    - "a taxonomy and survey of intrusion detection system design techniques network threats and datasets"
    - "glop enabling massively parallel incident response through gpu log processing"

Connected through hyperedge HE-3 (induced by source paper "on evaluating the effectiveness of the honeybot a case study"):
  with members:
    - "nosebreak attacking honeynets"

Connected through hyperedge HE-4 (induced by source paper "the rise of certificate transparency and its implications on the internet ecosystem"):
  with members:
    - "large scale classification of ipv6 ipv4 siblings with variable clock skew"
    - "towards better internet citizenship reducing the footprint of internet wide scans by topology aware prefix selection"

Question: Please tell me which class the center node belongs to. The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
