A Blockchain Based Framework Secured by ECDSA to Curb Drug Counterfeiting

The counterfeit problem has become so huge that it has drawn a significant attention among researchers and policy makers. The fake drug industry is worth of 10 billion dollar per year as estimated by ‘ASSOCHAM’ in 2017. Also estimated by WHO about a million die per year due to fake drugs. The dispensation of fake drugs is the pivotal concern, specially in developing countries like India. One of main reason in drug counterfeiting is imperfect supply chain. There are many loop holes in our current policy of drug supply chain management system. In the present scenario of supply chain, either the information is not shared between the parties during the hand off process at all or a little or irrelevant information is shared. Once a party transfer the drug to another party, the first party doesn't know what happens to the drugs there after. The counterfeit drug not only affect the health condition of patient or the financial loss of genuine manufacturer but also it is posing serious threat to the socio-economic status of the society. In this paper, we explain details of the drug counterfeit along with a little history of the pharmacy industry and its impact on different areas and also to counter the counterfeits using Blockchain technology. Using Blockchain technology we explained here how to add traceability, visibility, and security to the drug supply chain. This proposed system will track the drugs from its origin from the manufacturer to the end the consumer.

Elliptic Curve Cryptography-Based Signcryption Scheme with a Strong Designated Verifier for the Internet of Things

It has scenarios in which the real-world object is transferring data over an insecure wireless network. The security in IoT became more challenging because of the low computational and communication capacity of the object. The proposed signcryption scheme is a combination of a digital signature and symmetric key encryption in a single logical unit, which reduces the computational complexity as compared to the traditional signature, then encryption process along with the digital signature of the sender can only verify by the designated verifier. The computational and communication overhead of the elliptic curve cryptography (ECC) scheme have less because of short key length with the same security level as compared to other public key cryptosystem. The security hardness of the scheme is based elliptic curve discrete logarithm (ECDLP) and also provided various security requirements. The proposed scheme has low computational and communication overhead with low-power efficiency for IoT scenarios.

A secure ID-based signcryption scheme based on elliptic curve cryptography

Identity based cryptography is a distinct option for the traditional certificate based cryptosystem. Its principal thought is that every client utilises his identity information as his public key. Elliptic curve cryptosystem (ECC) have new received consistent attention because of their higher security per bit as compare to other cryptosystem. This paper presents a new identity based signcryption based on elliptic curve cryptography. Its security is dependent on elliptic curve discrete logarithm problem (ECDLP) and elliptic curve Diffie-Hellman problem (ECDHP). The proposed scheme can be very useful in low-end resource devices such as mobile communication, mobile banking, personal digital assistant (PDA) and internet of things (IoT).
