Certificate validation method and apparatus thereof

摘要: Virtual Private Network (VPN) client 1 and M access gateways 3, 4 5 each possess a public key cryptography pair (i.e., private key). If VPN sends Public Key Infrastructure (PKI) compliant signature based authentication information to an gateway or 5, the does not itself verify this information. Instead, it entrusts processing server 8, 9 10 receives verification result, via proxy 7. Conversely, generation of PKI be sent from is carried out by alone. The thus together implement support but have functions required for such apportioned between them.
