This discusses lightweight block ciphers, stream ciphers, and hybrid ciphers. The report evaluates security algorithms, comparing performance and robustness with the computational complexity of these techniques. The following question we address through our study is in line with the objective. 1) What is the need for the ...

Cryptography. , Volume 7, Issue 2 (June 2023) - 17 articles. Cover Story ( view full-size image ): The rise of quantum computing brings the threat of quicker brute force attacks, prompting the need for Post-Quantum Cryptography such as the NTRU cryptosystem. However, its main drawback is the lengthy polynomial multiplication process.

in this special issue focus on the emerging phenomenon of cryptocurrencies. Cryptocurrencies are digital financial assets, for which ownership and transfers of ownership are guaranteed by a decentralized technology. The rise of cryptocurrencies' value on the market and the growing popularity around the world open a number of challenges and concerns for business and ...

Cryptography is the study of assured communication procedure which allows only the sender and the intended person to review the message and the content shared. The simplest method used is the symmetric algorithm in which once the message is encrypted it is sent to the recipient along with its secret key. 2.

Step 4: XOR the sticker key with the LSB (MSB) to retrieve the actual bits of C Step 5: Convert the MSB of 8bit length to its ASCII code to retrieve the characters it represents Step6: Repeat the ...

Despite being 2000 years old, cryptography is still a very active field of . New needs and application fields, like privacy, the Internet of Things (IoT), physically unclonable functions (PUFs), post-quantum cryptography, and quantum key distribution, will keep fueling the work in this field. This book discusses quantum cryptography, lightweight cryptography for IoT, PUFs ...

A Feature should be a substantial original Article that involves several techniques or approaches, provides an outlook for future directions and describes possible applications. Feature are submitted upon individual invitation or recommendation by the scientific editors and must receive positive feedback from the ...

protection of data is essential in this digitized world and hence the need for techniques to aid in this process. Cryptography in general helps achieve three primary goals; confidentiality, integrity, and authenticity. The goal of confidentiality is to ensure and allow for authorized . Encryption is ubiquitous and unavoidable as it plays a pivotal role in ...

In this direction, the main contributions are listed below: This reviews the privacy-preserving crypto-techniques used in well-known blockchain platforms. Additionally, it provides a comparative analysis of the studied blockchain platforms and the studied techniques against three criteria: crypto-technique category, quantum resistance, and anonymity type.

They are broadly classified into two types: (a) symmetric-key and (b) public-key cryptosystems. In symmetric-key cryptography, the same key is shared between the sender and the receiver. But in public-key cryptography, the sender sends the encrypted data to the receiver using receiver's public key. The receiver decrypts the data using his/her ...
