ST1284-01A8RL Article About

IP ESP The basic idea is to encapsulate the entire IP packet, or only the upper layer protocol ESP encapsulates the data, and the vast majority of ESP data encryption. State in the pipeline for the current ESP encrypted added a new IP header, which can be used for IP packet routing on the Internet. Receiver to take down the IP header, and then the ESP decryption, process, and take down the ESP header, then the original IP packet or a higher level protocol data as a normal IP packet, as for processing. In RFC 1827 makes provision for the format of ESP, RFC 1829 specified in the cipher block chaining mode to use ESP encryption and decryption of data encryption standard. While other algorithms and state are also available, but some countries control the import and export of such products also must be considered. Some countries even have a private encryption restrictions.
In addition, enterprises have to wait for Windows 7, need to pay close attention to them from the Windows XP time. Schuster said. Customers should consider the overall situation, "What is the risk to skip, and if you can accept the transfer to the 7 schedule?"
