Description

The SIO_DATA_AUTHENTICATION option specifies whether or not the standard file data sent over the network should be 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 two 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.

Values

option is the specification for whether or not the data is authenticated.

Valid values for option are:

  • yes
    Data authentication is required. The standard file data transfers are authenticated regardless of UCMD Server's authentication option.
  • no
    Data authentication is not required for the standard file. It is still possible for UCMD Server to request data authentication.

Default is no.
