Title:
Double shielded Public Key Cryptosystems
Authors: Xiaofeng Wang, Chen Xu, Guo Li, Hanling Lin, Weijian Wang
Abstract:By introducing extra shields on Shpilrain and Ushakov’s Ko-Lee-like protocol based on the decomposition problem of group elements we propose two new key exchange schemes and then a number of public key cryptographic protocols. We show that these protocols are free of known attacks. Particularly,if the entities taking part in our protocols create their private keys composed by the generators of the Mihailova subgroups of Bn, we show that the safety of our protocols are very highly guarantied by the insolvability of subgroup membership problem of the Mihailova subgroups.
