we working on game in java. user authentication using rest api made in php.

i'm using sessions store uid , game stores session in cookiestore. we've come conclusion isn't secure enough. thought temporary token, 'attackers' somehow able tokens himself. use api secret key, attackers might able reverse-engineer game.
