In recent years, many multimedia and image encryption techniques based on chaotic maps have been proposed. Recently, a new signal security system called Two-Dimensional Circulation Encryption Algorithm (TDCEA) was proposed for real-time multimedia data transmission. There exist some essential security defects in TDCEA. This paper gives an analysis on the security of TDCEA and proposed enhanced encryption algorithm. Proposed encryption scheme is based on two digital chaotic maps, which in turn are used to generate two different chaotic sequences.
