Cryptography has been used from time immemorial for preserving the confidentiality of data/information in storage or transit. Thus, cryptography research also evolving classical Caesar cipher to modern cryptosystems, based on modular arithmetic contemporary cryptosystems quantum computing. The emergence computing poses a major threat arithmetic, whereby even computationally hard problems which constitute strength ciphers could be solved polynomial time. This triggered post-quantum design and...

In this paper, we investigate the issues of data and users' privacy in decentralized environments. We propose a novel security privacy-preserving protocol for blockchain that addresses limitations existing approaches, mainly anonymity unlinkability identities transactions. highlight benefits our proposed protocols across various use cases theoretically analyze its efficiency robustness.

Thus, cryptography research also evolving classical Caesar cipher to modern cryptosystems based on modular arithmetic contemporary quantum computing. The emergence computing imposes a major threat whereby, even computationally hard problems which constitute strength ciphers could be solved deterministic time. This triggered post-quantum order design and develop...

In this paper, we examine and propose a solution for the challenges of sharing genome sequence data querying on cloud server in per-sonalized medicine scenarios. We develop privacy-preserving, secure efficient personalized medicine. The that making use stream cipher-based homomorphic transciphering server, to show effectiveness scenario. This paper also provides comparative analysis well-known existing encryption solutions BGV FV schemes combined with FLIP cipher demonstrate efficiency...

In this paper, a scheme is proposed for parallel-pipelined implementation of the multialphabet arithmetic-coding algorithm used in lossless data compression. Using scheme, it possible to parallelize both encoding and decoding operations respectively compression decompression. The performance order 0 1 models have been evaluated compared with existing sequential implementations terms ratios as well execution time using Canterbury corpus benchmark set files. also facilitates hardware...

We consider Initial Public Offering (IPO) on blockchains while preserving privacy using Secure Multiparty Computation (MPC), which allows participants to perform a computation secret data. provide "MPC as service", where users requiring distributes shares of their data MPC workers who run an protocol the and return result. Previous work by Benhamouda et al. considered IPO over Hyperledger Fabric. improve providing tighter easier integration in Fabric library SCALE-MAMBA. explain obtained...
