    • A method is disclosed for establishing data integrity and non-repudiation without hashing and without performing a bit to bit comparison of the message. The method includes: generating a random symmetric key for use with a symmetric encryption algorithm; generating a random sequence having a plurality of elements; separating a message into a plurality of blocks, wherein each block has a size less than or equal to the block size of the symmetric algorithm less the size of a digital signature of one of the plurality of elements; generating a signature for each of the plurality of elements; encrypting a concatenation of each of the plurality of blocks of the message with a corresponding signature, the encrypting performed with the symmetric encryption algorithm and the random symmetric key; and communicating the encrypted concatenation to a gaming device.
    • 公开了一种用于建立数据完整性和不可否认性而不具有哈希的方法,并且不执行消息的位比较。 该方法包括:生成与对称加密算法一起使用的随机对称密钥; 产生具有多个元素的随机序列; 将消息分离成多个块,其中每个块具有小于或等于所述对称算法的块大小的尺寸,其小于所述多个元素之一的数字签名的大小; 为所述多个元素中的每个元素生成签名; 将所述消息的所述多个块中的每一个的级联与对应的签名加密,使用所述对称加密算法和随机对称密钥进行加密; 以及将所述加密连接传送到游戏设备。

    • A system is disclosed for establishing data integrity and non-repudiation without hashing and without performing a bit to bit comparison of the message. The system includes necessary hardware and/or software to generate a random symmetric key for use with a symmetric encryption algorithm; generate a random sequence having a plurality of elements; separate a message into a plurality of blocks, wherein each block has a size less than or equal to the block size of the symmetric algorithm less the size of a digital signature of one of the plurality of elements; generate a signature for each of the plurality of elements; encrypt a concatenation of each of the plurality of blocks of the message with a corresponding signature, the encryption being performed using the symmetric encryption algorithm and the random symmetric key; and communicating the encrypted concatenation from the gaming server to a gaming device.
    • 公开了一种用于建立数据完整性和不可否认性而不进行散列的系统,并且不执行消息的位比较。 该系统包括用于生成随机对称密钥以用于对称加密算法的必要的硬件和/或软件; 生成具有多个元素的随机序列; 将消息分离成多个块,其中每个块具有小于或等于所述对称算法的块大小的尺寸,所述大小小于所述多个元素之一的数字签名的大小; 为所述多个元素中的每一个生成签名; 将消息的多个块中的每一个的级联与对应的签名加密,使用对称加密算法和随机对称密钥执行加密; 以及将所述加密级联从所述游戏服务器传送到游戏设备。
