1. It involves the secrecy, integrity, undeniability of information transmission. 涉及信息传输的机密性、完整性、不可抵赖性等等。
2. The system can guarantee the secrecy of content transmission with other features like simplicity for identification, content authentication, key management and anonymity for payments. 系统可以保证数字内容的安全传输，同时具有用户身份认证、内容认证和密钥管理方面的简单性，系统还支持用户的匿名消费。
3. Most cable codes are examples in which secrecy isn't the purpose. Cable codes were developed to lower transmission costs by reducing message length. Codes work at the level of meaning; 例如，大多数电报码并不以保密为目的，电报的意义仅在于降低传递信息的成本。
4. Transmission bandwidth and speed of cat7 lan cable reach 600MHz, 1. 2GHz bandwidth and 10Gbps transmission frequency. Support to transmission of kilomega ethernet network. 七类线的传输带宽和速率达到600 MHz，达到1。2 GHz的带宽和10 Gbps的传输速率，支持千兆位以太网的传输。
5. Mount the transmission on a transmission jack and secure the transmission with safety chains. 在一个变速箱千斤顶上放置变速箱并用安全带固定变速箱。
