根据我的经验，这最好是一个社会工程问题，而不是一个编程问题。与其专注于让作弊变得不可能，不如专注于通过消除作弊动机来让它变得无聊。例如，如果主要动机是公开可见的高分，那么简单地延迟高分的显示时间就可以通过消除作弊者的正反馈循环来显著减少作弊。

你说的是所谓的“客户信任”问题。因为客户端(在这种现金中，运行在浏览器中的SWF)正在做它设计要做的事情。保存高分。

问题是，你想要确保“保存分数”请求来自你的flash电影，而不是任意的HTTP请求。一种可能的解决方案是在请求时(使用flasm)将服务器生成的令牌编码到SWF中，该令牌必须随请求一起保存高分。一旦服务器保存了该分数，令牌就过期了，不能再用于请求。

这样做的缺点是，用户每次加载flash电影只能提交一个高分——你不得不强迫他们刷新/重新加载SWF，然后他们才能再次播放新的分数。

It is only possible by keeping the all game logic at server-side which also stores the score internally without knowledge of the user. For economical and scientific reasons, mankind can not apply this theory to all game types excluding turn-based. For e.g. keeping physics at server-side is computationally expensive and hard to get responsive as speed of hand. Even possible, while playing chess anyone can match AI chess gameplay to opponent. Therefore, better multiplayer games should also contain on-demand creativity.

没有办法使它完全不可攻击，因为它很容易反编译swf，一个熟练的开发黑客可以跟踪您的代码，并找出如何绕过您可能使用的任何加密系统。

如果你只是想通过使用TamperData这样的简单工具来阻止孩子作弊，那么你可以生成一个加密密钥，在启动时传递给SWF。然后，在将高分传递回PHP代码之前，使用http://code.google.com/p/as3crypto/之类的东西对高分进行加密。然后在服务器端解密，然后将其存储到数据库中。

在接受的答案中，tqbf提到你可以对分数变量进行内存搜索(“我的分数是666，所以我在内存中寻找666这个数字”)。

这是有办法的。我在这里有一门课:http://divillysausages.com/blog/safenumber_and_safeint

基本上，你有一个对象来存储你的分数。在setter中，它将您传递给它的值与一个随机数(+和-)相乘，而在getter中，您将保存的值除以随机乘数以获得原始值。这很简单，但有助于停止记忆搜索。

另外，看看PushButton引擎背后的一些人的视频，他们谈论了一些对抗黑客的不同方法:http://zaa.tv/2010/12/the-art-of-hacking-flash-games/。他们是这门课背后的灵感。

I made kind of workaround... I had a gave where scores incremented ( you always get +1 score ). First, I started to count from random num (let's say 14 ) and when I display the scores, just showed the scores var minus 14. This was so if the crackers are looking for example for 20, they won't find it ( it will be 34 in the memory ). Second, since I know what the next point should be... I used adobe crypto library, to create the hash of what the next point should be. When I have to increment the scores, I check if the hash of the incremented scores is equal to the hash is should be. If the cracker have changed the points in the memory, the hashes are not equal. I perform some server-side verification and when I got different points from game and from the PHP, I know that cheating were involved. Here is snippet ot my code ( I'm using Adobe Crypto libraty MD5 class and random cryptography salt. callPhp() is my server side validation )

private function addPoint(event:Event = null):void{
            trace("expectedHash: " + expectedHash + "  || new hash: " + MD5.hash( Number(SCORES + POINT).toString() + expectedHashSalt) );
            if(expectedHash == MD5.hash( Number(SCORES + POINT).toString() + expectedHashSalt)){
                SCORES +=POINT;
                callPhp();
                expectedHash = MD5.hash( Number(SCORES + POINT).toString() + expectedHashSalt);
            } else {
                //trace("cheat engine usage");
            }
        }

使用这种技术+ SWF混淆，我能够阻止饼干。此外，当我将分数发送到服务器端时，我使用自己的小型加密/解密功能。类似这样的代码(服务器端代码不包括在内，但你可以看到算法并用PHP编写):

package  {

    import bassta.utils.Hash;

    public class ScoresEncoder {

        private static var ranChars:Array;
        private static var charsTable:Hash;

        public function ScoresEncoder() {

        }

        public static function init():void{

            ranChars = String("qwertyuiopasdfghjklzxcvbnm").split("")

            charsTable = new Hash({
                "0": "x",
                "1": "f",
                "2": "q",
                "3": "z",
                "4": "a",
                "5": "o",
                "6": "n",
                "7": "p",
                "8": "w",
                "9": "y"

            });

        }

        public static function encodeScore(_s:Number):String{

            var _fin:String = "";

            var scores:String = addLeadingZeros(_s);
            for(var i:uint = 0; i< scores.length; i++){
                //trace( scores.charAt(i) + " - > " + charsTable[ scores.charAt(i) ] );
                _fin += charsTable[ scores.charAt(i) ];
            }

            return _fin;

        }

        public static function decodeScore(_s:String):String{

            var _fin:String = "";

            var decoded:String = _s;

            for(var i:uint = 0; i< decoded.length; i++){
                //trace( decoded.charAt(i) + " - > "  + charsTable.getKey( decoded.charAt(i) ) );
                _fin += charsTable.getKey( decoded.charAt(i) );
            }

            return _fin;

        }

        public static function encodeScoreRand(_s:Number):String{
            var _fin:String = "";

            _fin += generateRandomChars(10) + encodeScore(_s) + generateRandomChars(3)

            return _fin;
        }

        public static function decodeScoreRand(_s:String):Number{

            var decodedString:String = _s;
            var decoded:Number;

            decodedString = decodedString.substring(10,13);         
            decodedString = decodeScore(decodedString);

            decoded = Number(decodedString);

            return decoded;
        }

        public static function generateRandomChars(_length:Number):String{

            var newRandChars:String = "";

            for(var i:uint = 0; i< _length; i++){
                newRandChars+= ranChars[ Math.ceil( Math.random()*ranChars.length-1 )];
            }

            return newRandChars;
        }

        private static function addLeadingZeros(_s:Number):String{

            var _fin:String;

            if(_s < 10 ){
                 _fin = "00" + _s.toString();
            }

            if(_s >= 10 && _s < 99 ) {
                 _fin = "0" + _s.toString();
            }

            if(_s >= 100 ) {
                _fin = _s.toString();
            }           

            return _fin;
        }


    }//end
}

然后我把这个变量和其他的假变量一起发送，它就会迷失在其中…对于小型flash游戏来说，这是一项艰巨的任务，但当涉及到奖品时，有些人就会变得贪婪。如果你需要任何帮助，给我写个便条。
