TASE.2 Protocol stack configuration
The TASE2 protocol stack configuration specifies communication parameters and is a collection of entries containing information about OSI Transport and OSI Application layers objects.
Each entry is comprised of attributes that describe the object. All the configuration data are structured using JSON.
Each entry shall be mapped with the corresponding configuration function in the chosen implementation protocol library.

TLS configuration
The TASE2 standard can also be used with TLS to realize secure and authenticated connections.
Parameters are needed to set up the TLS secured connection:
private_key | client private key | valid private key | YES |
own_cert | client certificate | valid certificate | YES |
ca_certs | allows to specify the ca certificates if not included in the owner certificate | list of valid certificates | NO |
remote_certs | allows to specify the server certificates, so if specified, only these certificates are accepted | list of valid certificates | NO |
Fledge's certificate store allows certificates to be stored and used by the south plugins.
