3093731 - How to set up TLS (Transport Layer Security) in SAP IQ16.X -- SAP IQ

What is TLS?

• Transport Layer Security (TLS), an IETF standard protocol, secures client/server communications using digital certificates and public-key cryptography.
  
  • Transport layer security enables encryption, tamper detection, and certificate-based authentication.
  • Transport layer security can be used to secure communications between the database server and client applications.
  • Transport Layer Security (TLS) is the successor protocol to Secure Sockets Layer (SSL).
    
    
• Secure communication begins with an exchange of messages (a handshake) including server authentication.
  
  • Transport layer security uses server certificates to establish and maintain a secure connection.
  • A unique certificate files is created for each server.
  • These are generally called “identity” files.
  • The identity file resides with the database server.
    
    
• Server authentication can be used for SAP IQ client/server communication.
  
  • A database client verifies the identity of an SAP IQ database server.
  • This is called “authentication”.
  • The client ensures that the server it is contacting is the correct server.
  • The client uses a trusted certificate that was used to sign the server’s identity certificate.
  • The database administrator keeps the server identity certificate safe on the database server computer. 
  • Only a copy of the trusted certificate is provided to the clients running on other computer systems.
