Wireless sensor networks are already deployed in numerous occasions. As this technology matures towards wider adoption, security will become an increasingly important requirement. However, resource and cost constraints for the low-complexity sensor nodes r ...
Since the late 70’s, several public key cryptographic algorithms have been proposed. Diffie and Hellman first came with this concept in 1976. Since that time, several other public key cryptosystems were invented, such as the well known RSA, ElGamal or Rabin c ...
In 1984, C.H. Bennet and G. Brassard proposed a new protocol aimed to solve the problem of symmetric cryptographic key exchange. This protocol was called BB84 after the name of its authors. While a traditional method would rely on public key cryptography ( ...
Abstract—Resource and cost constraints remain a challenge for wireless sensor network security. In this paper, we propose a new approach to protect confidentiality against a parasitic adversary, which seeks to exploit sensor networks by obtaining measureme ...
We report direct evidence of enhanced spontaneous emission in a photonic crystal light-emitting diode (LED) at telecom wavelength (lambda similar to 1300 nm). This result is crucial to obtain an electrically driven single photon source with high extraction ...
