A New Hybrid Cryptosystem Involving DNA,Rabin, One Time Pad and Fiestel

Information security is a crucial need in the modern world. Data security is a real concern, and many customers and organizations need to protect their sensitive information from unauthorized parties and attackers. In previous years, numerous cryptographic schemes have been proposed. DNA cryptography is a new and developing field that combines the computational and biological worlds. DNA cryptography is intriguing due to its high storage capacity, secure data transport, and massive parallel computing. In this paper, a new combination is proposed that offers good security by combining DNA, the Rabin algorithm, one time pad, and a structure inspired by Fiestel. This algorithm employs two keys. The first key is a DNA OTP key which is used for only one secure communication session. The second key, which combines the public and private keys, is a Rabin key. Additionally, by using a Feistel inspired scheme and randomness provided by DNA, the ciphertext is made harder to obtain without the private key.Comment: 11 page

Physical Turing Machines and the Formalization of Physical Cryptography

We introduce an extension of the standard Turing machine model, so-called Physical Turing machines, and apply them in a reductionist security proof for a standard scheme from physical cryptography

RFID Technology in Intelligent Tracking Systems in Construction Waste Logistics Using Optimisation Techniques

Construction waste disposal is an urgent issue for protecting our environment. This paper proposes a waste management system and illustrates the work process using plasterboard waste as an example, which creates a hazardous gas when land filled with household waste, and for which the recycling rate is less than 10% in the UK. The proposed system integrates RFID technology, Rule-Based Reasoning, Ant Colony optimization and knowledge technology for auditing and tracking plasterboard waste, guiding the operation staff, arranging vehicles, schedule planning, and also provides evidence to verify its disposal. It h relies on RFID equipment for collecting logistical data and uses digital imaging equipment to give further evidence; the reasoning core in the third layer is responsible for generating schedules and route plans and guidance, and the last layer delivers the result to inform users. The paper firstly introduces the current plasterboard disposal situation and addresses the logistical problem that is now the main barrier to a higher recycling rate, followed by discussion of the proposed system in terms of both system level structure and process structure. And finally, an example scenario will be given to illustrate the system’s utilization
