Multicomponent reactions provide key molecules for secret communication

Quantum Secret Communication without an Encryption Key

Quantum cryptographic methods increase security over classical methods. To date, quantum algorithms aim to distribute a secret key to be used afterwards to encrypt messages. The method described in this paper does not use an encryption key at all. An array of qubits is transmitted from the source to the destination with the message encoded in the phase of the qubit. The secrecy of the message d...

Lattice Codes for Secure Communication and Secret Key Generation

In this work, we study two problems in information-theoretic security. Firstly, we study a wireless network where two nodes want to securely exchange messages via an honestbut-curious bidirectional relay. There is no direct link between the user nodes, and all communication must take place through the relay. The relay behaves like a passive eavesdropper, but otherwise follows the protocol it is...

Multicomponent Reactions

Multicomponent reactions

Chemistry as a central science is facing a steadily increasing demand for new chemical entities (NCE). Innovative solutions, in all kinds of disciplines that depend on chemistry, require new molecules with specific properties, and their societal consequences are fundamental and pioneering. However, NCE not only demand a realistic structural space but also their feasibility poses challenges to s...

Synthesis of Phosphorus Derivatives via Multicomponent Reactions

Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields.
