A. Thomas, Dr. Gireesh K. T., and Ashok Kumar Mohan, “Neighbor Attack Detection in Internet of Things”, in Advanced Computational and Communication Paradigms, Singapore, 2018.[Abstract] Internet of Things (IoT) hegemonies all other technological development the world has seen so far. 6LoWPAN is emerging as the next generation protocol of IoT. 6LoWPAN protocol enables the resource constrained embedded device to connect to the Internet through IPv6. Routing Protocol for Low Power and Lossy Networks (RPL) is specifically designed as a routing protocol for resource constrained device and it is adaptable with the 6LoWPAN. There are many attacks which make RPL insignificant to achieve its desired objectives. Neighbor attack is momentous and is capable of disrupting possible routing path. In this paper, we proposed intrusion detection system which can detect neighbor attack in RPL protocol and a secure root process to prevent the effect of attack on this protocol. The IDS is incorporated by considering location information and received signal strength to identify malicious node. We have also incorporated secure root process which can rectify disruption in routing path after detecting attacks. This method can act as an optimum method for resources constrained environment.

Using some forensics frameworks we can able to hide and retrieve data in any format both in Windows and Linux operating systems. Whatever the data are made to be hidden in the disk, some frameworks are very good at its carving technique which it analyze and give all the parts of the disk or any other memory devices. In this paper I have clearly explained how memory forensics frameworks analyze the memory of the hard disk drives. Some specific utilities are capable and designed specifically only for windows Operating system and at the same way some forensics frameworks are designed specifically for Linux based distributions. Here I have analyzed few frameworks that are currently good in conducting a digital forensic investigation. These frameworks are for a human resources internal investigation where unauthorized investigation into the server, or to select frameworks to conduct new investigation and these frameworks and suits will assist to conduct analysis of memory forensic, forensic analysis of hard drive, forensic imaging, forensic image exploration, forensic imaging and mobile forensics. Such that, they all designed in such a way that it has the features to bring back in whole depth analyzed report of its merits in its technique flow and about what's under the system hood. More »» |

A. Gopalakrishnan, Vineti, E., Ashok Kumar Mohan, and Dr. M. Sethumadhavan, “The Art of Piecewise Hashing: A step toward better evidence provability”, Journal of Cyber Security and Mobility, vol. 7, pp. 109-130, 2018.[Abstract] The integrity of digital evidence is believed to be the paramount trait in the world of cyber forensics. Cybercrime investigators face myriad challenges in the process similar to accommodating the call for bulk digital evidence. In due course extraction of useful information while maintaining the integrity and absolute protection against data degradation is mandatory. In this manuscript, we propose a novel approach by applying cryptographic hashing technique to only selected significant portions of the digital evidence, so even if the overall hash does not match, investigators could still verify the integrity of those critical sections of the evidence.We put forward two notions in this manuscript; former is heterogeneous piecewise hashing which is a flexible version of the piecewise hashing strategy, and latter is a novel evidence certification strategy which formalizes evidence provability process completely. © 2018 the Author(s).

Ashok Kumar Mohan, Thampy, R. V., and Praveen, K., “Data Hiding in Slack Space Revisited”, International Journal of Pure and Applied Mathematics, vol. 118, pp. 3017-3025, 2018.[Abstract] In the current world scenario storing of any data securely in any storage medium is of major concern. Transferring any secret data without being compromised by the attacker is becoming difficult day by day. In such a situation, using the slack space for storing and retrieving secret information can be a great boon. Slack space is nothing but the unused space in a disk cluster. Here, the slack space of private cloud and slack space of the files which is being uploaded to the private cloud is considered for hiding and retrieving the secret information. Slack sizes of files are determined using hex editors. MD5 hashes of the path of the files containing slack and key are taken and sorted in the ascending order. Message to be hidden is encrypted and is divided into chunks of data depending on slack sizes of files which has been reordered by its corresponding sorting of MD5 hashes of file paths along with the key. Divided chunks of data are hidden in the slack spaces accordingly. Mapping of MD5 hashes of file paths along with the key and slack size will help in the retrieval of hidden information from slack spaces. The secret data will be securely hidden in the slack spaces of the private cloud. The idea of keeping secret data in slack space of private cloud is more advantageous because cloud itself provides security than usual physical storage media and moreover that, the possibility of being detected by an attacker is often less as slack space often contains data which could not be easily detected by normal analysis. Along with this, a secret sharing algorithm is proposed for splitting and sharing the secret data among cloud users and the file slack space in the cloud gives the accessibility of secret data More »» |

Sethumadhavan, and Santhya R, “A Selective Generation of Hybrid Random Numbers via Android Smart Phones”, International Journal of Pure and Applied Mathematics, vol. 118, no. 8, pp. 311-317, 2018.[Abstract] The True Random Number Generator (TRNG) is an important module for countless cryptographically secure appliances. TRNG generation technique requires custom made hardware with quantum phenomena, which on the whole are expensive research components. A secure and sound TRNG design is anticipated at this time, which is based on the permutation of sensor feeds and combination of noise patterns from the peripherals of any Android smartphone. The source for this generator is the selected features from the in-built hardware components namely accelerometer, gyroscope, magnetometer, WiFi signal measure, cell tower information, GPS coordinates and battery thermal noise. Additionally, Process ID (PID) of the corresponding Android processes is given as key vector to augment the entropy and also addresses some of the security concern like confidentiality, integrity and availability of the authentic sources. . Hardware-Based Random Number Generator (HRNG) can be achieved by combing the source of the user, their corresponding parameters and the measure of imperfection. More »» |

Ashok Kumar Mohan, Dr. M. Sethumadhavan, and A, A. Devi, “Wireless Security Auditing: Attack Vectors and Mitigation Strategies”, Procedia Computer Science, vol. 115, pp. 674–682, 2017.[Abstract] Wireless security is concise on protecting the resources connected to the wireless network from unauthorized access. Wi-Fi Protected Access II (WPA2) is a predominant variety of cryptography based wireless security protocol, which is crafted to be robust and can prevent all the wireless attacks. But numerous organizations explicitly like educational institutions remains vulnerable due to lack of security. By auditing the vulnerabilities and performing the penetration testing, it is possible to review the causes of the issues indicted over the network. Wireless security auditing is anticipated to be an exact blend of attack scenario and the well matched audit policy checklist provides a benchmark for a sheltered wireless network in safe hands.

Krithika, Ashok Kumar Mohan, and Sethumadhavan, M., “Jordan Center Segregation: Rumors in Social Media Networks”, in Security in Computing and Communications: 5th International Symposium, SSCC 2017, Manipal, India, September 13–16, 2017, Proceedings, vol. 746, S. M. Thampi, Pérez, G. Martínez, Westphall, C. Becker, Hu, J., Fan, C. I., and Mármol, F. Gómez, Eds. Singapore: Springer Singapore, 2017, pp. 146–158.[Abstract] Social media networks have gained a lot of popularity among the people by rapidly spreading rumors inquiring a variety of human affairs. Nowadays people simply tend to hype over social media for publicity or promotion which is the prime source for all deception activities online. The data shared in the midst of social media may be spreading a bogus news online and sooner or later they will be sorted off the record as rumors, but meanwhile the rumor might have done an adequate amount of damage to the subject. Current day rumor Segregation practice aims no more than identifying the rumor in the reign, days after its first forecast. The anticipated model will serves as a precise way out for isolating a rumor by calculating the preparatory source of the rumor by the use of Jordan source center with SI, SIR, and SIRI infection models. Jordan source center is the best optimal source calculator which overcomes the error rate, infection rates and other parameters when compared to other centrality estimators from the marketplace. It helps in finding the source of a common social media rumor and proceeding further to cleanse the infections and trim down their forged impact over the social media networks. More »» |

Suresh, Dash, S. Subhransu, and Panigrahi, K. Bijaya, Eds. New Delhi: Springer India, 2015, pp. 447–455.[Abstract] The Internet users for the purpose of easy memorizing select a weak password and reuse it along many Web sites vulnerable to password stealing and reuse due to rapid growth of cloud computing. Sturdy one-time password (S-OTP) provides with easy remembrance and prevention of password reuse using personal Android mobile phone without the necessity of sending an SMS and can be integrated into any original user authentication system without contradicting the overall security. Also, in the worst cases, if the mobile phones are stolen, it is made unfeasible by means of two-dimensional SHA3 and MD5 forward hashing with unique and secure hard-coded seed information from mobile device.

Ashok Kumar Mohan and Dr. Venkataraman D., “The Forensic Future of Social media Analysis using Web Ontology”, International Conference on Advanced Computing and Communication Systems (ICACCS -2017). 2017.[Abstract] Whenever some user posts on social media networks, knowingly or unknowingly their activity is registered in countless online repositories. This exposes parts of the data to be publicly available; as a consequence of this a forensic analyst can reveal past activities, reconstruct a biased timeline and recover deleted data of the suspect. Movie ontology maps the input from movies and videos of user via facebook graph API to produce adaptive results of user activity related to their entertainment activities. Movie ontology will demonstrate how to reconstruct the social behavior of the user from the file and how to interpret the gained information as a potential source of evidence in digital forensic investigations.
