would be both difficult and insecure. I evaluated the standard in 1999 and concluded that its unnecessary complexity had a “devastating effect” on security. Today, end-to-end encryption still isn’t ubiquitous on the Internet, although it’s getting better. A second example: in the secret government-only standards process for digital cellular

that the NSA ensured that algorithms used to encrypt voice traffic between the handset and the tower are easily breakable, and that there is no end-to-end encryption between the two communicating parties. The result is that your cell phone conversations can easily be monitored. Both of these were probably part of NSA

AS POSSIBLE Governments should have the goal of encrypting as much of the Internet+ as possible. There are many facets to this. One: we need end-to-end encryption for communications. This means that all communications should be encrypted from the sender’s device to the receiver’s device, and that no one in

is called link-by-link encryption; everything going through a particular data link is encrypted. If it takes place at higher layers, it is called end-to-end encryption; the data are encrypted selectively and stay encrypted until they are decrypted by the intended final recipient. Each approach has its own benefits and drawbacks

layers for transmission. This approach avoids the encryption/decryption problem at the physical layer. By providing end-to-end encryption, the data remains encrypted until it reaches its final destination (see Figure 10.2). The primary problem with end-to-end encryption is that the routing information for the data is not encrypted; a good cryptanalyst can learn

communications architecture, like the applications layer or the presentation layer, then it can be independent of the type of communication network used. It is still end-to-end encryption, but the encryption implementation does not have to bother about line codes, synchronization between modems, physical interfaces, and so forth. In the early days of

requires some intelligence and is not suitable for dumb terminals. Additionally, there may be compatibility problems with different types of computers.
