Pitfalls in public key cryptosystems based on free partially commutative monoids and groups.

We show that both proposals are vulnerable to chosen ciphertext attacks, and thus in the present form must be considered as insecure.5eng© 2005 Elsevier Ltd.Atribución-NoComercial-SinDerivadas 3.0 EspañaFinitely presented groupPublic key cryptographyWord problemresearch articleMatemáticashttps://doi.org/10.1016/j.aml.2005.11.014open access1037101041Applied Mathematics Letters19AR/0000032353
