Abstract
The following description is directed to encrypting the characteristics of network traffic. In one example, a method can include receiving an unencrypted link layer packet including a first payload of a first size. The method can include encrypting the first payload of the unencrypted link layer packet. The method can include generating an encrypted link layer packet including a second payload. The second payload can include the encrypted payload and a variable length padding field so that the second payload of the encrypted link layer packet is a different size than the first size of the first payload. The encrypted link layer packet can then be transmitted.
