Abstract
Techniques described herein enhance information security in contexts that utilize key management systems and other providers of cryptographic services. A user of a key, management system is able to use a secret that is outside the control of the key management system combined with a secret that is cryptographically protected by the key management system (e.g., by encryption using a key managed by the key management system) to generate a message encryption key, thereby rendering the secrets individually insufficient for access to data encrypted using the message encryption key.
