洗牌随机数生成规则：
洗牌随机数由三个玩家的公钥、预言机随机数、牌局id顺序拼接而成，其中玩家的公钥按照玩家进入牌局的顺序进行拼接；
将拼接后的字符串转为16进制得到该牌局的洗牌随机数；

public static String getRandSeries(String pubKey1, String pubKey2, String pubKey3, String id){
	SecureRandom random = new SecureRandom();
	String randSeries = byte2HexStr((pubKey1+pubKey2+pubKey3+random.nextInt()+id).getBytes());
	return randSeries;
