Recently, Tseng and Wu pointed out that the second protocol of Biswas’s two-party keys scheme based on the Diffie-Hellman technique has a security weakness and proposed a new protocol to remedy the weakness. In this article, we point out that Tseng-Wu’s protocol is vulnerable to a man-in-the-middle attack. An attacker could intercept, delete, or modify the communicated messages between two comm...

This paper provides the first analytical and practical treatment of entity authentication and authenticated key exchange in the framework of Tree Parity Machines (TPMs). The interaction of TPMs has been discussed as an alternative concept for secure symmetric key exchange. Several attacks have been proposed on the non-authenticated principle. Adding and some extra entity authentication method i...

Background Recent studies revealed that tumor-associated macrophages (TAMs) play a decisive role in the regulation of tumor progression by manipulating tumor oncogenesis, angiogenesis and immune functions within tumor microenvironments. Signal transducer and activator of transcription 3 (STAT3), which is a point of convergence for numerous oncogenic signalling pathways, is constitutively activ...
