System and Methodology for Decrypting Encrypted Media

1. A system comprising: a memory that has stored thereon computer executable components; and a processor that executes the following computer executable components stored in the memory: a frame monitoring component that monitors a frame to determine if a signal byte is prepended to the frame, wherein bits in the signal byte indicate information about the frame comprising information about whether the frame is encrypted and information about whether an initialization vector follows the signal byte; a generation component that generates the initialization vector in response to the signal byte indicating that there is an encrypted frame and no initialization vector following the signal byte; and a decryption component that uses the initialization vector to decrypt the encrypted frame.

2. The system of claim 1 , wherein size of the initialization vector is sixteen bytes.

3. The system of claim 1 , wherein the generation component appends a last byte of a preceding encrypted frame one or more times to an end of a portion of data to form the initialization vector.

4. The system of claim 3 , wherein the portion of data is a size of the previous frame and, if the size of the preceding encrypted frame is smaller than the predetermined size, the generation component appends a last byte of the preceding encrypted frame one or more times to an end of the portion of data to form the initialization vector having a predetermined size.

5. The system of claim 1 , wherein bits in the signal byte indicate that an additional signal byte follows the signal byte and that key data follows the signal byte.

6. The system of claim 5 , wherein the key data is used to obtain a new key from a key server.

7. The system of claim 1 , wherein the frame monitoring component determines if the encrypted frame is an intra frame or an inter frame.

8. The system of claim 7 , wherein the frame monitoring component determines that the initialization vector is prepended to the encrypted frame in response to determining that the encrypted frame is an intra frame.

9. The system of claim 7 , wherein the frame monitoring component determines that the encrypted frame is an intra frame or an inter frame based on bits in the signal byte.

10. The system of claim 7 , wherein the generation component generates the initialization vector from the portion of data from the previous encrypted frame in response to the frame monitoring component determining that the encrypted frame is an inter frame.

11. The system of claim 1 , wherein the frame monitoring component monitors signal bytes of a series of frames to detect an initialization vector in response to receiving information that one of the series of frames is encrypted.

12. A method comprising: employing a processor that facilitates execution of computer executable instructions stored on a non-transitory computer readable medium to implement operations, comprising: monitoring a frame to determine if a signal byte is attached to the frame, wherein bits in the signal byte provide information about the frame, wherein the information about the frame comprises information about whether the frame is encrypted and information about whether an initialization vector is prepended to the framed; generating the initialization vector in response to the signal byte indicating that the frame is an encrypted frame and that the initialization vector is not prepended to the frame; and decrypting the encrypted frame with the initialization vector.

13. The method of claim 12 , appending a last byte of a preceding encrypted frame one or more times to an end of a portion of data to form the initialization vector.

14. The method of claim 12 , analyzing the signal byte to identify data that is prepended to the encrypted frame.

15. The method of claim 12 , obtaining a key from a key server using key data in response to identifying that key data is prepended to the signal byte.

16. The method of claim 12 , further comprising: determining whether the encrypted frame is an intra frame or an inter frame based on bits in the signal byte.

17. The method of claim 12 , monitoring signal bytes of a series of frames to detect an initialization vector in response to receiving information that one of the series of frames is encrypted.

18. The method of claim 12 , further comprising: determining whether the encrypted frame is an intra frame or an inter frame.

19. The method of claim 18 , further comprising: monitoring for the initialization vector prepended to the encrypted frame in response to determining that the encrypted frame is an intra frame.

20. A non-transitory computer readable storage medium comprising computer-executable instructions, that in response to execution, cause a computing system to perform operations, comprising: monitoring a frame to determine if a signal byte is prepended to the frame, wherein bits in the signal byte provide information about the frame, wherein the information about the frame comprises information about whether the frame is encrypted and information about whether an initialization vector is prepended to the framed; generating the initialization vector in response to the signal byte indicating that the frame is an encrypted frame and that the initialization vector is not prepended to the frame; and decrypting the encrypted frame with the initialization vector.
