Clouds over a public key cryptosystem based on Lyndon words
We demonstrate that with the given specifications the Lyndon words based public key cryptosystem suggested by Siromoney and Mathew [Inform. Process. Lett. 35 (1990) 33-36] is susceptible to very simple ciphertext only attacks. Consequently, in the present form this system cannot be considered as sufficiently secure for cryptographic applications.
