OpenSSH should be able to do this. From the man pages:

The scheme is based on public-key cryptography: there are
where encryption and decryption are done using separate keys, and

is one such system. The idea is that each user creates a
key pair for authentication purposes. The server knows the public
and only the user knows the private key.
The file $HOME/.ssh/authorized_keys lists the public keys that are
mitted for logging in. When the user logs in, the ssh program
server which key pair it would like to use for authentication. The
server checks if this key is permitted, and if so, sends the user
ally the ssh program running on behalf of the user) a challenge, a
number, encrypted by the user=92s public key. The challenge can only
decrypted using the proper private key. The user=92s client then
the challenge using the private key, proving that he/she knows the
vate key but without disclosing it to the server."
If you can't solve your problems, post the specific problem you are
