Abstract
A method and a system to provide identity encapsulated cryptography are provided. A method may comprise receiving a user key to access a service. The service may be provided by an enterprise and hosted within a public cloud. A request for a country key assigned to a country of a user is transmitted and the country key is received. Session data resulting from the use of the service hosted within the public cloud is encrypted using the user key and the user key is encrypted using the country key. The encrypted session data and the encrypted user key are stored in the public cloud. The country key may be provided to a legal agency of the country of the user to decrypt session data of the user and to not decrypt session data of other users of another country.
