You can obtain a digitalcertificate from a well-known Certificate Authority (CA) such as VeriSign, orgenerate and sign your own certificate using functionality available on thisgateway. The gateway comes with a self-signed certificate, and this can bereplaced by one signed by a CA as per your networking requirements. A CAcertificate provides strong assurance of the server's identity and is a requirementfor most corporate network VPN solutions.A self certificate is a certificate issued by a CA identifying your device (or selfsignedif you don't want the identity protection of a CA). To request a selfcertificate to be signed by a CA, you can generate a Certificate Signing Requestfrom the gateway by entering identification parameters and sending to the CA forsigning. Once signed, the CA's Trusted Certificate and signed certificate from theCA are uploaded to activate the self-certificate validating the identity of thisgateway. The self certificate is then used in IPsec and SSL connections with peersto validate the gateway's authenticity.Cisco RV120W Administration Guide 107
