Joint SPIHT compression and selective encryption
We propose JCSE-SPIHT, an algorithm of joint compression and selective encryption based on SPIHT. We design a fast random insertion to accelerate the encryption from taking O(n2) time to O(n). JCSE-SPIHT can generate plaintext-dependent keystream by cryptographically secure PRNG. We exam the security of JCSE-SPIHT by traditional cryptanalysis and image processing techniques.
