This book constitutes the proceedings of the First International ICST Workshop, SEWCN 2009, held in Athens, Greece, in September 2009. The workshop emphasizes on new ideas for secure architectures and protocols to enhance the emerging wireless systems. The 7 selected full papers cover topics on applied cryptography, key management, vulnerability analysis, privacy, authentication, and intrusion detection for emerging wireless systems.
