Query: On the security of the Yen-Guo's domino signal encryption algorithm
  (DSEA)   Recently, a new domino signal encryption algorithm (DSEA) was proposed for
digital signal transmission, especially for digital images and videos. This
paper analyzes the security of DSEA, and points out the following weaknesses:
1) its security against the brute-force attack was overestimated; 2) it is not
sufficiently secure against ciphertext-only attacks, and only one ciphertext is
enough to get some information about the plaintext and to break the value of a
sub-key; 3) it is insecure against known/chosen-plaintext attacks, in the sense
that the secret key can be recovered from a number of continuous bytes of only
one known/chosen plaintext and the corresponding ciphertext. Experimental
results are given to show the performance of the proposed attacks, and some
countermeasures are discussed to improve DSEA.
