A Public-Key Approach of Selective Encryption for Images.
Feng Jiang, Paul Salama, Brian King · IUScholarWorks (Indiana University) · 2017
Data security protection is essential for most multimedia data transmissions today. Classical multimedia content protection is dominated by symmetric encryption methods. This paper explores the possibility of public-key media content encryption. The key problem to the asymmetric selective encryption is formalized and defined as the ＂bounded plaintext problem＂. Possible solutions to this problem are proposed. A public-key multimedia encryption model is developed and the implementation results are provided.
