Abstract
A value is associated with a token within a trust zone. The token is used in place of the value in operations executed within the trust zone. A key is defined for an entity outside of the trust zone. A processor encrypts the token using the key to form an encrypted token that cannot be decrypted by entities outside of the trust zone. The encrypted token is provided to the entity outside of the trust zone.
