DATA_AUTHENTICATION - UCMD Manager configuration option
Description
The DATA_AUTHENTICATION option specifies whether or not all data sent over the network is authenticated when using the UNVv2 protocol.
Generating a checksum value for each data block performs authentication. The checksum value is sent with the data block. The receiver generates a second checksum value for the data block. If the checksum values are not equal, the authentication fails. Failed authentication closes the network connection.
The checksum is generated with the MD5 Message Digest Algorithm by RSA Data Security, Inc.
DATA_AUTHENTICATION does not have any effect on the SSL/TLS protocol. See the DATA_SSL_CIPHER_LIST option for SSL/TLS data authentication.

Values
option is the specification for whether or not data is authenticated.
Valid values for option are:
- yes
Data authentication is required for the UNVv2 protocol. All network data transfers are authenticated regardless of UCMD Server's DATA_AUTHENTICATION option. - no
Data authentication is not required. However, the UCMD Server still can request data authentication via its DATA_AUTHENTICATION option.
Default is no.
