    • Methods and systems for encrypting and decrypting data are described. In one embodiment, a computing system determines a first initialization vector (IV) from another IV and a sequence number of a block of information, and hashes the first IV to create a hash. The computing system then determines a first block from the first block of information and the first hash and enciphers the first block to generate a block of ciphertext. In another embodiment, the computing system deciphers the block of ciphertext to generate the first block, and determines the first IV from the other IV and a sequence number of a block of information. The computing system hashes the first IV to create a hash and determines a block of information corresponding to the first block of ciphertext from the first block and the hash.
    • 描述用于加密和解密数据的方法和系统。 在一个实施例中,计算系统从另一个IV和一个信息块的序列号确定第一初始化向量(IV),并且将第一个IV哈希建立一个散列。 然后,计算系统从第一个信息块和第一个散列确定第一个块,并加密该第一个块以产生一个密文块。 在另一个实施例中,计算系统解密密文块以产生第一块,并从另一个IV确定第一个IV和一个信息块的序列号。 计算系统对第一个IV进行散列以创建散列,并从第一个块和散列中确定与第一个密文块对应的信息块。

    • A security initialization system receives a first initialization request from a first requester to access a first database storing security data and stores context data for the first initialization request that identifies an initialization operation associated with the first database. The security initialization system receives a second initialization request from a second requester to access a second database storing security data and updates the context data to identify an initialization operation associated with the second database. The security initialization system receives a shut down request from one of the requesters, where the shut down request includes data for identifying a corresponding initialization operation in the context data. The security initialization system updates the context data to show that the corresponding initialization operation has a shut down request and determines whether a security module is to be shut down using the context data.
    • 安全初始化系统接收来自第一请求者的第一初始化请求以访问存储安全数据的第一数据库,并且存储用于识别与第一数据库相关联的初始化操作的第一初始化请求的上下文数据。 安全初始化系统从第二请求者接收第二初始化请求以访问存储安全数据的第二数据库,并更新上下文数据以识别与第二数据库相关联的初始化操作。 安全初始化系统从请求者之一接收关闭请求,其中关闭请求包括用于识别上下文数据中的对应的初始化操作的数据。 安全初始化系统更新上下文数据以示出相应的初始化操作具有关闭请求,并且确定是否使用上下文数据关闭安全模块。

    • A computer system, method and/or computer-readable medium provide independent data objects to a token in compressed form. The independent data objects are representative of security information associated with the token. The system includes an interface operable to communicate with a token, and a processor cooperatively operable with the interface. The processor is configured to determine a set of independent data objects that are associated with the token, and to aggregate the set of independent data objects associated with the token into a group. Also, the processor is configured for compressing the group into a unit of contiguous data, and writing the unit of contiguous data to the token via the interface.

    • A server, method and/or computer-readable medium system for secure communication includes a certificate authority for generating certificates signed by the certificate authority and associated public and private keys for a client. The server further includes a directory of client attributes and client virtual attributes. At least one of the client virtual attributes is for, when receiving a query for a client that cannot be located in the directory, requesting the certificate authority to dynamically generate a certificate and associated public and private key for the client, and for storing the dynamically generated certificate and public key as a client attribute in the directory.
    • 用于安全通信的服务器,方法和/或计算机可读介质系统包括用于生成由证书机构签名的证书的证书颁发机构以及用于客户端的相关联的公钥和私钥。 服务器还包括客户端属性和客户机虚拟属性的目录。 客户端虚拟属性中的至少一个用于当接收到不能位于目录中的客户端的查询时,请求证书颁发机构为客户端动态生成证书和关联的公钥和私钥,并存储动态 生成的证书和公钥作为目录中的客户端属性。

    • An apparatus, method and/or computer-readable medium protects against use of a unity key in a public key infrastructure (PKI). A public key and a private key are acquired according to the PKI. A message is encrypted by the public key to obtain ciphertext. A portion of the ciphertext is compared with a portion of the message. If the portion of the ciphertext is substantially equal to the portion of the message, a larger portion of the ciphertext is compared with a larger portion of the message to determine if the ciphertext is substantially equal to the message. If the ciphertext is substantially equal to the message, the ciphertext is rejected.
    • 设备,方法和/或计算机可读介质防止在公共密钥基础设施(PKI)中使用统一密钥。 根据公钥基础设施获取公钥和私钥。 消息由公钥加密以获得密文。 将密文的一部分与消息的一部分进行比较。 如果密文的部分基本上等于消息的部分,则将较大部分的密文与消息的较大部分进行比较,以确定密文是否基本上等于该消息。 如果密文基本上等于消息,则密文被拒绝。
