Abstract
A device (3000) for processing an encrypted data stream (3001), wherein decryption messages are provided for decrypting each segment (1403) of the encrypted data stream (3001), wherein each decryption message comprises a number of decryption elements, wherein the device (3000) comprises a detection unit (3002) for detecting the number of decryption elements per decryption message, and a determining unit (3003) for determining a position for providing the decryption messages in relation to the sequence of the segments (1403), based on the detected number.

39. A device (3000) for processing an encrypted data stream (3001), wherein decryption messages are provided for decrypting each segment (1403) of the encrypted data stream (3001),
wherein each decryption message comprises a number of decryption elements, wherein the device (3000) comprises a determining unit (3003) for determining a position for providing the decryption messages in relation to the sequence of the segments (1403), characterized in that the device further comprises a detection unit (3002) for detecting the number of decryption elements per decryption message, the number of decryption messages being indicative of the position to be determined; wherein the determining unit (3003) further determines the position for providing the decryption messages in relation to the sequence of the segments (1403), based on the detected number of decryption elements per decryption message. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)

58. A computer-readable medium, in which a computer program of processing an encrypted data stream (3001), wherein decryption messages are provided for decrypting each segment (1403) of the encrypted data stream (3001), wherein each decryption message comprises a number of decryption elements, is stored, which computer program, when being executed by a processor, is adapted to control or carry out the following method steps:
-
determining a position for providing the decryption messages in relation to the sequence of the segments (1403) characterized in that the method further comprises detecting the number of decryption elements per decryption message, the number of decryption messages being indicative of the position to be determined; and wherein the step of determining further determines the position for providing the decryption messages in relation to the sequence of the segments (1403), based on the detected number of decryption elements per decryption message.

59. A program element of processing an encrypted data stream (3001), wherein decryption messages are provided for decrypting each segment (1403) of the encrypted data stream (3001), wherein each decryption message comprises a number of decryption elements, which program element, when being executed by a processor, is adapted to control or carry out the method steps of:
-
determining a position for providing the decryption messages in relation to the sequence of the segments (1403) characterized in that the method further comprises detecting the number of decryption elements per decryption message, the number of decryption messages being indicative of the position to be determined; and wherein the step of determining further determines the position for providing the decryption messages in relation to the sequence of the segments (1403), based on the detected number of decryption elements per decryption message.
