Satellite network authentication scheme based on ELGamal digital signature
Huang Wang-zong · 2011
To deal with satellite interference and illegal use of satellite resources,the factors of satellite communication network are analyzed,and the safety certification requirements of satellite network are taken into consideration comprehensively.A two-way satellite network security authentication scheme based on ElGamal digital signature is proposed.The ElGamal digital signature algorithm itself is improved in this scheme.The speed of ElGamal digital signature is accelerated and the expense of communication performance is econo-mized.Actual application in the information transmission of a special satellite communication system shows that this method overcome the low efficiency and complex process authentication existed in traditional certification.
