查询词典 message block

The symmetric algorithm is a traditional algorithm, it is easy and efficient, and so it is still being popular used. The stream cIPher and the block cIPher are two part of the symmetric algorithm. The symmetric algorithm uses the key to control the key stream generator, and then the generator produces a random stream. We can get the cIPher by xor the message and the random stream by bit. In the field of communication and code, the stream cIPher has always been the key cIPher of the military affairs and foreign affairs.

对称密码体制分为序列密码和分组密码两类，序列密码以密钥控制密钥流发生器，产生一随机序列，用这个随机序列和明文信息逐位异或，就得到密文，其加密单元为比特。

Because lacking of perfect secure email system, domestic govements are not permitted to use email to transfer message in case it was stealed, which block our country"s e-business/e-government affair"s popularization and information industrys progress.

由于缺乏功能完善的安全电子邮件系统，为避免邮件泄露国家机密，国内党政机关禁止任何与外界的电子邮件联系，极大地阻碍了电子政务/电子商务的推广，阻碍了我国的信息化进程。

Negotiate to already came originally end, but the message that subsequently interior came out to the plan receives block and die without known cause.

原本谈判已至尾声，但随后内部传出了计划遇阻并无疾而终的消息。

In an actual format, however, keypads would probably fill more than one block, and the number of blocks in a message would be variable.

在一个实际的格式，不过，键盘可能会填补一个以上的块，以及有多少块在贺电中，将变。

For 4-pass HAVAL, we describe a practical attack for finding two-block collisions with 2~(36) computations. Using the more complex message modification technique, the complexity can be improved to 2~(30). In addition, we show that collisions for 5-pass HAVAL can be found with about 2~(123) computations, which is the first attack more efficient than the birthday attack.

对于4-PassHAVAL，首次给出了一个复杂度为2~(36)的具有两个消息分组的碰撞，使用更复杂的消息修改技术，该攻击的复杂度能够降低到2~(30)；对于5-pass HAVAL，首次给出了一种优于生日攻击的理论攻击方法，复杂度小于2~(123)。

Ticket printing based on Internet is one of the key problems. In allusion to the insufficient of conventional printing solution based on Socket and COM component, the paper designed distributed ticket-printing solution with Web Services and Windows Form technique, which eliminate the affect of Firewalls block during remote ticket-data transferring. Besides, the solution utilizes adequately the standard coding rules of SOAP message to customize data structure of ticket.

基于Internet的票券打印是系统需要解决的关键性问题之一，总结传统的基于Socket和COM组件的印票方案所存在的不足，结合Web Services技术和Windows Form技术实现了分布式的票券打印，解决了远程票券传输时由于防火墙的阻隔作用而带来的问题，并充分利用SOAP消息规范的编码规则设计了票券数据结构。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
