PowerShell script failure on remote execution

On executing a PowerShell Remote Script I am getting an error like following

Invoke-Command : Exception calling "ToXmlString" with "1" argument(s): "The requested operation cannot be completed. Th

    $rsa = New-Object System.Security.Cryptography.RSACryptoServiceProvider
