The purpose of this paper is to present an improvement of the Needham-Schroder public key protocol. This new protocol will use partial quotients issue from the continued fraction expansion of some irrational numbers to secure the authentication between two principals. We introduce a new approach in the use of pseudo-random numbers, because besides using these numbers to provide uniqueness and timeliness guarantees, we use them to ensure that nobody can guess the identity of the sender. We also keep this new protocol secure against the Lowe attack, without taking the solution suggested by Lowe. This protocol remains fast although we compute some partial quotients during the authentication process.

The task is to identify salient named entities from a set of named entities. 'Salience' of a named entity indirectly depends on the author. He may not emphasize on all the named entities. Suppose the tweet 'Google executive Dan Fredinburg dies in Everest Avalanche Nepal Earthquake'. The author emphasize on the named entity 'Dan Fredlinburg' more than other named entities such as Google, Mount Everest or Nepal.

The key exchange protocol is one of the most elegant ways of establishing secure communication between pair of users by using a session key. The passwords are of low entropy, hence the protocol should resist all types of password guessing attacks. Recently ECC-3PEKE protocol has been proposed by Chang and Chang. They claimed the protocol is secure, efficient and practical. Unless their claims Yoon and Yoo presented an Undetectable online password guessing attack on the above protocol. A key recovery attackwas proved on ECC-3PEKE protocol using the Undetectable online password guessing attack proposed by Yoon and Yon. In the present paper an Impersonation attack on ECC-3PEKE protocol using the Undetectable online password guessing attack proposed by Yoon and Yon is demonstrated.

In this paper, a computational science guided soft computing based cryptographic technique using Ant Colony Intelligence (ACICT) has been proposed. In this proposed approach at first a metamorphosed based strategy is used to produce intermediate cipher text. Finally, ACI generated keystream is used to further encrypt the intermediate cipher text to produce the final cipher text. In this approach an ant agent having a pheromone deposition consisting of a group of alphanumeric characters is called a key stream and each character in the key stream is known as key. The key stream length always be less than or equal to the plaintext to be encrypt. The keystream generation is based on distribution of characters in the plaintext. Instead of transmitting the plain keystream to the receiver, further encryption is done on keystream and encrypted keystream get transmitted to the receiver. Parametric tests are done and results are compared with some existing classical techniques, which show comparable results for the proposed system.

Password authentication with smart card is one of the simplest and efficient authentication mechanisms to ensure secure communication over insecure network environments. Recently, Tsai et al. proposed an improved password authentication scheme for smart card. Their scheme is more secure than the other previous schemes. In this paper, we show Tsai et al.’s scheme is vulnerable to password guessing attack and has computational overhead. Furthermore, we propose an enhanced password authentication scheme to eliminate the security vulnerability and enhance the overhead. By presenting concrete analysis of security and performance, we show that the proposed scheme cannot only resist various well known attacks, but also is more efficient than the other related works, and thus is feasible for practical applications.

TEXTUAL passwords have been the most widely used authentication method for decades. Comprised of number sand upper- and lower-case letters, textual passwords are considered strong enough to resist against brute force attacks. However, a strong textual password is hard to memorize and recollect .Therefore, users tend to choose passwords that are either short or from the dictionary, rather than random alphanumeric strings. Various graphical password authentication schemes were developed to address the problems and weaknesses associated with textual passwords. Based on some studies such as those in , humans have a better ability to memorize images with long-term memory(LTM) than verbal representations. Image-based passwords were proved to be easier to recollect in several user studies As a result, users can set up a complex authentication password and are capable of recollecting it after a long time even if the memory is not activated periodically. The human actions such as choosing bad passwords for new accounts and inputting passwords in an insecure way for later logins are regarded as the weakest link in the authentication chain [16]. Therefore, an authentication scheme should be designed to overcome these vulnerabilities. In this paper, we present a secure graphical authentication system named Pass Matrix that protects users from becoming victims of shoulder surfing attacks when inputting passwords in public through the usage of one-time login indicators. A login indicator is randomly generated for each pass-image and will be useless after the session terminates. The login indicator provides better security against shoulder surfing attacks, since users use a dynamic pointer to point out the position of their passwords rather than clicking on the password object directly.

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.

With more memory available, system performance of three Dell devices increased, which can translate to a better user experience Conclusion When your system has plenty of RAM to meet your needs, you can efficiently access the applications and data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that with more memory available, three Dell PCs delivered better performance and took less time to complete the Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring your system with more RAM can help keep processes running smoothly, enabling you to do more without compromising performance.

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “The Role of Taxonomy and Ontology in Semantic Layers” at a webinar hosted by Progress Semaphore on April 16, 2024. Taxonomies at their core enable effective tagging and retrieval of content, and combined with ontologies they extend to the management and understanding of related data. There are even greater benefits of taxonomies and ontologies to enhance your enterprise information architecture when applying them to a semantic layer. A survey by DBP-Institute found that enterprises using a semantic layer see their business outcomes improve by four times, while reducing their data and analytics costs. Extending taxonomies to a semantic layer can be a game-changing solution, allowing you to connect information silos, alleviate knowledge gaps, and derive new insights. Hedden, who specializes in taxonomy design and implementation, presented how the value of taxonomies shouldn’t reside in silos but be integrated with ontologies into a semantic layer. Learn about: - The essence and purpose of taxonomies and ontologies in information and knowledge management; - Advantages of semantic layers leveraging organizational taxonomies; and - Components and approaches to creating a semantic layer, including the integration of taxonomies and ontologies
