In order to efficiently encrypt multimedia streams delivered in real-time environments, a Fast Encryption Algorithm for Multimedia (FEA-M) was proposed. Cryptanalyses of this technique have identified its weaknesses and an improved variant has been suggested. In this paper, the authors identify further weak-nesses in the original FEA-M and also in the improved variant. Their solution provides message integrity, guarantees zero packet loss and protects against specific known plaintext attacks.
