New Paper on Encryption Workarounds

The widespread use of encryption has triggered a new step in many criminal investigations: the encryption workaround. We define an encryption workaround as any lawful government effort to reveal an unencrypted version of a target’s data that has been concealed by encryption. This essay provides an overview of encryption workarounds. It begins with a taxonomy of the different ways investigators might try to bypass encryption schemes. We classify six kinds …Read More
