Security Analysis of a Chaos-Based Encryption Technique to Protect ECG Packets For Time Critical Telecardiology Applications
The chaotic system and cryptography have some common features. Due to the close relationship between chaotic system and
cryptosystem, researchers try to combine the chaotic system with cryptosystem. In this study, security analysis of an encryption algorithm
which aims to encrypt the EKG data with chaotic keys was performed. Inthe conducted cryptanalysis study, it was shown that encryption
algorithm has not sufficient capacity to provide necessary security level. Furthermore, it was shown that the secret key can be obtained with
only one plaintext/ciphertext pair with chosen-plaintext attack.
