Compression can be combined with encryption in this case LCP frames and the control frames used for other protocols canīe encrypted. Note that unlike what we saw in compression, The frame as encrypted, decrypt it and restore the original frame withĠx8021 as the Protocol value.The discussionĮxactly one PPP data frame. The receivingĭevice would see the value 0x0053 in the Protocol field, recognize In a PPP frame with a Protocol value of 0x0053. IP data in PPP, the unencrypted frame would have a value of 0x8021 (hex) Protocol field, so the receiving device knows what higher layerįor example, if we use IPCP to encapsulate When the data is decrypted, this value is used to restore the original Protocol value is actually prepended to the data before encryption. The data comes from since we still need to know this, the original Recall that in a regular unencryptedįrame, the Protocol field indicates what layer three protocol Is used with multiple links and the links are encrypted independently,Ī different value is used: 0x0055.
