Abstract
Systems, methods and computer readable media for providing users with encrypted content data associated with a service are disclosed. A device may receive first content data. The device may encrypt the first content data using a first key to obtain first encrypted data. The device may generate second encrypted data by applying a cipher substitution to the first encrypted data using a second key. The device may cause to send the second encrypted data to a second device.
Claims18
A device comprising:
- at least one computer processor;
- and
- at least one non-transitory storage medium storing computer-executable code comprising:
- receiving first content data;
- encrypting the first content data using a first key to obtain first encrypted data;
- generating second encrypted data by applying a cipher substitution to the first encrypted data using a second key;
- generating third encrypted data by applying a second cipher substitution to the second encrypted data using a third key, wherein the second cipher substitution is different from the first cipher substitution;
- and
- causing to send the third encrypted data to a second device.

6 more elements
A method comprising:
- receiving, by one or more processors, first content data;
- encrypting, by the one or more processors, the first content data using a first key to obtain first encrypted data;
- generating, by the one or more processors, second encrypted data by applying a cipher substitution to the first encrypted data using a second key;
- and
- generating, by the one or more processors, third encrypted data by applying a second cipher substitution to the second encrypted data using a third key, wherein the second cipher substitution is different from the first cipher substitution;
- and
- causing to send, by the one or more processors, the third encrypted data to a second device.
