英文摘要	Recently, a new signal security system called tdcea (two-dimensional circulation encryption algorithm) was proposed for real-time multimedia data transmission. this paper gives a comprehensive analysis on the security of tdcea. the following security problems are found: (1) there exist some essential security defects in tdcea; (2) two known-plaintext attacks can break tdcea; (3) the chosen-plaintext and chosen-ciphertext versions of the aforementioned two known-plaintext attacks can break tdcea even with a smaller complexity and a better performance. some experiments are given to show the security defects of tdcea and the feasibility of the proposed known-plaintext attacks. as a conclusion, tdcea is not suitable for applications that require a high level of security.
