Sentence examples for multimedia data encryption from inspiring English sources

In order to achieve high performance, we build up Master-Slave design architecture with the aid of TMS320C6701-DSP to construct a PHPS implementation scheme for the multimedia data encryption and decryption based on the framework of virtual-optics.

This work investigates the problem of efficient multimedia data encryption.

Traditional ciphers like DES, 3DES, IDEA, RSA, or AES are less efficient for real-time secure multimedia data encryption systems and exhibit some drawbacks and weakness in the high stream data encryption [3, 4].

The technologies used for security of multimedia data include encryption, fingerprinting, and watermarking.

Experimental results show that the new cipher has satisfactory security with a low cost, which makes it a potential candidate for encryption of multimedia data such as images, audios and even videos.

The other category of WSN applications that use FPGA based sensor nodes are multimedia data transmission[19, 20], sensor data security related to encryption algorithms[21, 22], environmental monitoring[23 25].

Therefore, chaotic dynamics is expected to provide a fast and easy way for building superior performance cryptosystems, and the properties of chaotic maps such as sensitivity to initial conditions and random-like behavior have attracted the attention to develop data encryption algorithms suitable for secure multimedia communications.

2) Encryption Data encryption is an efficient means of preventing unauthorized access of sensitive data.

Product cipher, data encryption scheme in which the ciphertext produced by encrypting a plaintext document is subjected to further encryption.

The efficiency and security of the proposed encryption scheme makes it an ideal choice in secure media applications where a large amount of multimedia data has to be encrypted/decrypted in real time.

However, encryption and decryption procedures are time-consuming processes, and they are thus not suitable for high-volume multimedia data [7], digital images, and videos.
