Recently, a novel plaintext-related RGB image encryption scheme has been proposed, where the security is strengthened by associating the initial condition and control parameter of one logistic map with total plain image characteristics. This paper points out its weakness that the secret location storing the total characteristics cannot adapt to different plain images. Accordingly, we propose a strategy to break this encryption scheme by applying chosen/known plaintext attacks, where the data complexity of attack is reduced to the minimum. The experimental results prove that all the secret matrices can be revealed effectively. Meanwhile, three corresponding improvements are given to guarantee its security, which help to design more secure plaintext-related cryptosystems in the future.
