One way is to encrypt the files with GPG or TrueCrypt. GPG can encrypt individual files, but AFAIK will require you to use the commandline. TrueCrypt, on the other hand, has a GUI but since it creates containers with complete filesystems inside, you'll have to format it with a filesystem which both OS:es can read, e.g. FAT32.
When the files are encrypted any mode of transfer should be secure (given a strong enough passphrase).
