Certificate Issuing using Proxy Signature and Threshold Signature in Self-initialized Ad Hoc Network
Jeonil Kang, Younggeun Choi, Koon-Soon Kim, DaeHun Nyang · Information Security and Cryptology · 2007
In ad hoc network, especially in the environment which the system authority only exists at the beginning of the network, it is very important problem how to issue the certificates in self-initialized public key scheme that a node generates its certificate with public and private key pair and is signed that by the system authority. In order to solve this problem, early works present some suggestions; remove the system authority itself and use certificate chain, or make nodes as system authorities for other nodes' certificates. In this paper, we suggest another solution, which can solve many problem still in those suggestions, using proxy signature and threshold signature, and prove its performance using simulation and analyse its security strength in many aspects.
