Cryptanalysis of a family of self-synchronizing chaotic stream ciphers
David Arroyo, Gonzalo Alvarez, Jose Maria Amigo +1
Unimodal maps have been broadly used as a base of new encryption strategies. Recently, a stream cipher has been proposed in the literature, whose keystream is basically a symbolic…
Cryptanalysis of a new chaotic cryptosystem based on ergodicity
David Arroyo, Gonzalo Alvarez, Shujun Li +2
This paper analyzes the security of a recent cryptosystem based on the ergodicity property of chaotic maps. It is shown how to obtain the secret key using a chosen-ciphertext attac…
On the security of a new image encryption scheme based on chaotic map lattices
David Arroyo, Rhouma Rhouma, Gonzalo Alvarez +2
This paper reports a detailed cryptanalysis of a recently proposed encryption scheme based on the logistic map. Some problems are emphasized concerning the key space definition and…
Cryptanalysis of a computer cryptography scheme based on a filter bank
David Arroyo, Chengqing Li, Shujun Li +1
This paper analyzes the security of a recently-proposed signal encryption scheme based on a filter bank. A very critical weakness of this new signal encryption procedure is exploit…
Cryptanalysis of an image encryption scheme based on a new total shuffling algorithm
David Arroyo, Chengqing Li, Shujun Li +2
Chaotic systems have been broadly exploited through the last two decades to build encryption methods. Recently, two new image encryption schemes have been proposed, where the encry…
Analog Chaos-based Secure Communications and Cryptanalysis: A Brief Survey
Shujun Li, Gonzalo Alvarez, Zhong Li +1
A large number of analog chaos-based secure communication systems have been proposed since the early 1990s exploiting the technique of chaos synchronization. A brief survey of thes…
