摘要： Disclosed herein are methods and systems for configuring and using one or more block ciphering techniques in order to encrypt/decrypt serial data streams while maintaining cryptographic synchronization and attempting to minimize the amount of overhead introduced into the stream. The techniques disclosed herein may be used to encrypt and decrypt serial data streams using a block cipher in a manner that can be substantially transparent to the devices involved in the serial communication session. For example, the serial user data may be left unframed by the encryption device while monitoring for opportunistic times to transmit framed cryptographic synchronization information during periods of relative inactivity in an asynchronous serial data stream. A cryptographic device implementing the techniques described herein may be configured to implement one or more of an encryption device or a decryption device.
摘要翻译：这里公开了用于配置和使用一个或多个块加密技术以便加密/解密串行数据流同时保持加密同步并且尝试最小化引入到流中的开销的量的方法和系统。本文公开的技术可以用于以对于串行通信会话中涉及的设备基本上透明的方式使用分组密码来加密和解密串行数据流。例如，串行用户数据可以由加密设备保持不成帧，同时监视在异步串行数据流中的相对不活动期间发送帧加密同步信息的机会时间。实施本文描述的技术的加密设备可以被配置为实现加密设备或解密设备中的一个或多个。

摘要： Methods for configuring and utilizing a configurable data guard (CDG) implemented on a hardware-based programmable logic device are disclosed. The CDG may include integrated circuit portions comprising a plurality of arrays of generic comparison operations and a plurality of arrays of generic action operations. The CDG may receive a data guard configuration. The CDG may perform an authentication and integrity check procedure on the received data guard configuration. The CDG may configure a plurality of guard primitives based on the data guard configuration. Each guard primitive may be configured from at least one generic comparison operation and at least one generic action operation. The guard primitives may be used to enforce the complex data guard rules that correspond to the data guard configuration.
