X.509 Certificate Authentication
X.509 is a client-certificate authentication that requires an HTTPS connection to SAP Mobile Platform Server, which can authenticate users based on their personal X.509 certificates.
X.509 is a standard for digital certificates, and provides the strongest form of authentication security in SAP Mobile Platform by managing authentication across platforms and out to the network edge.
This form of authentication always uses the X.509 User Certificate authentication provider. Clients using this form of authentication must connect to the server on the two-way HTTPS port (the default port number is 8082). For authentication to succeed, the certificate authority (CA) certificate used to sign the user's certificate must be in the SAP Mobile Platform keystore.
