摘要：
V. Simanaitis, A. Liutkevicius, A. Vrubliauskas, E. Kazanavicius, D. Imbrasas. Efficient MPEG-2 Transport Stream Encryption Method for Low Processing Power Mobile Devices // Electronics and Electrical Engineering. - Kaunas: Technologija, 2012. - No. 2(118). - P. 81-88. Video stream encryption is the main method for the protection of intellectual property in modern digital rights management systems (DRM). Existing encryption methods ensure very high protection level of encrypted content, but at the same time are very resources demanding, making them hardly suitable for low processing power mobile end-user devices. This paper presents partial MPEG-2 transport stream encryption method, which is suitable for such low power user terminals. The experimental evaluation of proposed method show that encryption and decryption times, comparing with standard full encryption, are reduced from 3 (static video) up to 9 times (dynamic video), making proposed method a good choice for low processing power decryption devices. Ill. 6, bibl. 14, tabl. 4 (in English; abstracts in English and Lithuanian).
