Simple Authenticated Multiple Key Exchange Protocol for Ubiquitous Computing
Eun‐Jun Yoon, Kee-Young Yoo · 2011
In 2011, Cheng-Ma proposed an improved authenticated multiple key exchange (AMKE) protocol based on bilinear pairings with reflection attack resilience. However, Chang-Ma's AMKE protocol designed inefficiently because it requires additional pairing computations and scalar multiplications on an elliptic curve to prevent their proposed reflection attacks. Based on this motivation, this paper proposes a simple authenticated multiple key exchange (SAMKE) protocol. Compared with the related AMKE protocols, the proposed SAMKE protocol is more efficient and holds stronger security. As a result, the proposed SAMKE protocol is more suitable for practical application such as secure key exchange in the ubiquitous and pervasive computing setting.
