Abstract:
1. A client device comprising a processor and a memory, wherein the processor is configured to: receive encrypted data from at least one remote device, wherein the encrypted data has been encrypted with a first key; attempt to decrypt the encrypted data using a second key initially stored on the client device; determine that the encrypted data was not decrypted using the second key; in response to determining that the encrypted data was not decrypted using the second key, transmit stop data stored on the client device to the at least one remote device to indicate to the at least one remote device that the encrypted data was not decrypted using the second key, wherein the stop data represents a command to the at least one remote device to cease transmitting data encrypted with the first key to the client device; and wherein the stop data is pre-encoded using a cryptographic operation and stored on the client device prior to receiving the encrypted data and prior to determining that the encrypted data was not decrypted using the second key.
