    • Disclosed is a method for evaluating resistance to cryptanalysis of a cipher structure having a diffusion element including a linear transformation placed between differently-sized confusion elements at an input and an output of the diffusion element. A generalized minimum number of non-zero symbols at the diffusion element's input and output is determined. The diffusion element's input is divided into subset inputs, each having a size corresponding to the size of each confusion element at the diffusion element input. For each subset input, a subset number of non-zero symbols at the subset input and the diffusion element output is determined. Each subset number is summed to generate a summed subset number. The summed subset number is subtracted from the generalized minimum number to generate a worst-case number. An upper bound of a maximum differential characteristic probability is calculated and used to evaluate the cipher structure.
    • 公开了一种用于评估具有扩散元件的密码分析电阻的方法,该扩散元件包括放置在扩散元件的输入端和输出端的不同大小的混淆元件之间的线性变换。 确定扩散元件输入和输出处的非零符号的通用最小数量。 扩散元件的输入被分成子集输入,每个子集具有与扩散元素输入处的每个混淆元素的大小相对应的大小。 对于每个子集输入,确定子集输入处的非零符号的子集数量和扩散元素输出。 将每个子集数相加以生成一个总和子集。 从广义最小数字中减去总和子集数,以生成最坏情况数。 计算最大微分特征概率的上限,并用于评估密码结构。

    • A method for obtaining a secure connection between a first server and a client. The method may comprise establishing a secure communication session between a second server and the client, wherein the second server is trusted by the first server, and the second server is configured to authenticate the client. The client may receive a client token, wherein the client token contains data associated with the first server, the second server, the client, and a digital signature. Then, the client may request secure communication access to the first server, wherein the request includes transferring the client token to the first server. Finally, the client may receive a grant of secure communication access to the first server based on authentication of the client by the first server, wherein the authentication is based on the client token validating the client and the digital signature validating the client token.
    • 一种用于获得第一服务器和客户端之间的安全连接的方法。 该方法可以包括在第二服务器和客户端之间建立安全通信会话,其中第二服务器被第一服务器信任,并且第二服务器被配置为认证客户端。 客户端可以接收客户令牌,其中客户端令牌包含与第一服务器,第二服务器,客户端和数字签名相关联的数据。 然后,客户机可以请求对第一服务器的安全通信访问,其中该请求包括将客户端令牌传送到第一服务器。 最后,客户端可以基于第一服务器对客户端的认证来接收对第一服务器的安全通信访问许可,其中认证基于验证客户端的客户端令牌和验证客户机令牌的数字签名。
