Yes, there is a way...
Suppose you want to cp some files from machine B to A using SCP. Follow
the steps:

 1. User X generates private/public key using ssh-keygen on Machine A.
     "Don't enter password during key generation"

 2. Now  ~X/.ssh/identity will have user's private key on machine A.

 3.  Append  ~X/.ssh/identity.pub to  ~/.ssh/authorizedkeys on Machine
B.
      This is user's public key on remote machine B.

 4.  Enable RSA authentication (per user based) on machine B in the
config file sshd_config.
      Make "permitemptypasswords yes". Restart SSH Daemon on machine B.

 5. Now try SCP from machine A using command
     scp user@MachineB:/Full/Path/To/File MachineADirPath

This procedure worked in our environment. This is quite useful if you
want to copy a list of
known files using SCP without giving password.
