Extension of Cube Attack with Probabilistic Equations and its Application on Cryptanalysis of KATAN Cipher

Zahra Eskandari; Abbas Ghaemi Bafghi

Volume 12, Issue 1 , January 2020, , Pages 1-12


  Cube Attack is a successful case of Algebraic Attack. Cube Attack consists of two phases, linear equation extraction and solving the extracted equation system. Due to the high complexity of equation extraction phase in finding linear equations, we can extract nonlinear ones that could be approximated ...  Read More

OT-Feature Extraction on Scrambled Images with Instantaneous Clustering for CBIR Scheme in Cloud Computing

K. Nalini Sujantha Bel; I.Shatheesh Sam

Volume 13, Issue 1 , January 2021, , Pages 1-17


  A novel feature extraction algorithm using Otsu’s Threshold (OT-features) on scrambled images and the Instantaneous Clustering (IC-CBIR) approach is proposed for Content-Based Image Retrieval in cloud computing. Images are stored in the cloud in an encrypted or scrambled form to preserve the privacy ...  Read More

A New Variant of the Winternitz One Time Signature Based on Graded Encoding Schemes

Hossein Oraei; Massoud Hadian Dehkordi

Volume 14, Issue 1 , January 2022, , Pages 1-11


  Digital signature schemes are used to guarantee for non-repudiation and authenticity of any kind of data like documents, messages or software. The Winternitz one-time signature (WOTS) scheme, which can be described using a certain number of so-called “function chains”, plays an important ...  Read More

Cloud Computing Threats, Vulnerabilities and Countermeasures: A State-of-the-Art

Suryateja Satya Pericherla

Volume 15, Issue 1 , January 2023, , Pages 1-58


  Cloud computing created a revolution in the way IT organizations and IT teams manage their internal digital resources and workloads. One major drawback or limitation of cloud computing, among others, is security. Cloud computing is plagued by a plethora of threats and vulnerabilities, with new ones being ...  Read More

CPA on COLM Authenticated Cipher and the Protection Using Domain-Oriented Masking

Mohsen Jahanbani; Nasour Bagheri; Zynolabedin Norozi

Volume 12, Issue 2 , July 2020, , Pages 67-80


  Authenticated encryption schemes are important cryptographic primitives that received extensive attention recently. They can provide both confidentiality and authenticity services, simultaneously. Correlation power analysis (CPA) can be a thread for authenticated ciphers, similar to the any physical ...  Read More

Privacy Preserving Attribute-Based Encryption with Conjunctive Keyword Search for E-health Records in Cloud

Aniseh Najafi; Majid Bayat; Hamid Haj Seyyed Javadi

Volume 13, Issue 2 , July 2021, , Pages 87-100


  The advent of cloud computing in the healthcare system makes accuracy and speed increased, costs reduced, and health services widely used. However, system users are always seriously concerned about the security of outsourced data. The ciphertext-policy attribute-based encryption (CP-ABE) is a promising ...  Read More
