TL;DR: It is pointed out that Zhou's encryption scheme is not secure enough from strict cryptographic viewpoint because the dynamical degradation of the computerized piecewise linear chaotic map employed by Zhou et al. induces many weak keys to cause large information leaking of the plaintext.

TL;DR: This Letter points out why the original chaotic encryption scheme is so vulnerable to the proposed four attacks, and presents an improved encryption scheme to obtain higher security.

TL;DR: CVES can be extended to support random retrieval of cipher-video with considerable maximal time-out; the extended CVES is called RRS-CVES (Random-Retrieval-Supported CVES), which is a universal fast encryption system and can be easily extended to other real-time applications.

TL;DR: This Letter analyzes a non-trivial defect in the enhanced Baptista-type cryptosystem, which produces errors in the decrypted data with a generally small but non-zero probability, and discusses how to rectify it.

TL;DR: The performance of Jakimoski–Kocarev attack on Baptista cryptosystem is re-study and it is found that it is not efficient enough as a practical attack tool.
