You could use a simple grep
Code:
$ if ! grep -v "=[^=]" authorized_keys; then
  echo "Found unknown key(s)"
fi

To process each key individually, perhaps a loop is better:
Code:
while read KEY; do
 [[ $KEY =~ =[^=] ]] || echo Unknown Key:
  echo $KEY
done < ~/.ssh/authorized_keys

SYNOPSIS

       dropbearkey -t type -f file [-s bits] [-y]

DESCRIPTION

       dropbearkey generates a RSA or DSS format SSH private key, and saves it to a file for the use with the dropbear(8) SSH 2 server.  Note that
       some SSH implementations use the term "DSA" rather than "DSS", they mean the same thing.

       -f file
	      Write the secret key to the file file.

       -s bits
	      Set the key size to bits bits, should be multiple of 8 (optional).

       -y     Just print the publickey and fingerprint for the private key in file.

EXAMPLE

       generate a host-key:
	# dropbearkey -t rsa -f /etc/dropbear/dropbear_rsa_host_key

       extract a public key suitable for authorized_keys from private key:
	# dropbearkey -y -f id_rsa | grep "^ssh-rsa " >> authorized_keys
