摘要： The present invention provides a solution to the problem of guaranteeing the integrity of software programs by encrypting all or part of each instruction of a program using a key based on all or part of one or a plurality of previous instructions, thus resulting in a different encryption key per instruction. The invention is applicable to software programs whose structures are not necessarily tree-like in nature and is also applicable when the program includes loops, jumps, calls or breaks etc. The invention allows for an exception to be flagged when an encrypted instruction is wrongly decrypted. There is no need for the first instruction to be in clear, since the instruction key may be appropriately initialized as required. The invention can be realized in software or entirely in hardware thereby eliminating the possibility of a third party intercepting a decrypted instruction or a decryption key.

摘要： The present invention provides a method for decrypting encrypted content transmitted from an operator to a plurality of users where said operator further provides security information allowing for the decryption of said content. The method has the advantage of satisfying the goal of providing the capability for detecting a fraudulent user who retransmits control words extracted from the security information to other users. The method provides for the achievement of the goal without incurring extra overhead in addition to the transmitted content and security information. The method makes use of control words which are based on multiple solutions provided by collisions in mathematical functions and involves the observation of choices of control words retransmitted by the fraudulent user.
摘要翻译：本发明提供了一种用于将从运营商发送的加密内容解密到多个用户的方法，其中所述操作者还提供允许解密所述内容的安全信息。该方法的优点在于满足提供检测从安全信息提取的控制字重发给其他用户的欺诈用户的能力的目的。该方法提供了实现目标，而不会产生额外的开销，除了传输的内容和安全信息。该方法利用基于数学函数中的冲突提供的多个解的控制词，并且涉及观察由欺诈用户重发的控制字的选择。

摘要： Data are converted between an unencrypted and an encrypted format according to the Rijndael algorithm, including a plurality of rounds. Each round is comprised of a fixed set of transformations applied to a two-dimensional array, designating states, of rows and columns of bit words. At least a part of the transformations are applied on a transposed version of the state, wherein rows and columns are transposed for the columns and rows, respectively.
摘要翻译：根据Rijndael算法，包括多个轮次，数据在未加密格式和加密格式之间进行转换。每一轮由应用于二维阵列的一组固定变换组成，指定位字的行和列的状态。至少一部分变换被应用在状态的转置版本上，其中行和列分别被转置用于列和行。

摘要： A method for implementing one-to-one binary functions defined on the Galois field GF(28) is very useful for forming fast and low power hardware devices regardless of the binary function. The method includes decoding an input byte for generating at least one bit string that contains only one active bit, and logically combining the bits of the bit string according to the binary function for generating a 256-bit string representing a corresponding output byte. The 256-bit string is then encoded in a byte for obtaining the output byte.
摘要翻译：用于实现在伽罗瓦域GF（28）上定义的一对一二进制函数的方法对于形成快速和低功率硬件设备是非常有用的，而不管二进制功能如何。该方法包括解码用于生成仅包含一个活动位的至少一个位串的输入字节，并且根据用于产生表示相应输出字节的256位串的二进制函数逻辑组合位串的位。然后将256位字符串编码为一个字节，以获得输出字节。
