This is been achieve by distinguishing spam from non-spam (self from non-self). In this paper, we propose an optimized technique for e-mail classification. This is done by distinguishing the characteristics of self and non-self that is been acquired from trained data set. These extracted features of self and non-self are then combined to make a single detector, therefore reducing the false rate. (Non-self that were wrongly classified as self). The result that will be acquired in this paper will demonstrate the effectiveness of this technique in decreasing false rate. KeywordsNegative selection; E-mail Classification; Algorithm; Self, Non-Self, Artificial Immune System, Classification accuracy.

The cryptographic systems security of public key depends on the complexity in solving mathematical problems. Quantum computers pose a threat to the current day algorithms used. This research presents analysis of two Hash-based Signature Schemes (MSS and W-OTS) and provides a comparative analysis of them. The comparisons are based on their efficiency as regards to their key generation, signature generation and verification time. These algorithms are compared with two classical algorithms (RSA and ECDSA) used in bitcoin transaction security. The results as shown in table II indicates that RSA key generation takes 0.2012s, signature generation takes 0.0778s and signature verification is 0.0040s. ECDSA key generation is 0.1378s, signature generation takes 0.0187s, and verification time for the signature is 0.0164s. The W-OTS key generation is 0.002s. To generate a signature in W-OTS, it takes 0.001s and verification time for the signature is 0.0002s. Lastly MSS Key generation, signature generation and verification has high values which are 16.290s, 17.474s, and 13.494s respectively. Based on the results, W-OTS is recommended for bitcoin transaction security because of its efficiency and ability to resist quantum computer attacks on the bitcoin network.

The essence of steganography as an art of hiding information was examined using the wavelet approach. The algorithms developed and exhibited in block diagrams were experimentally examined with encrypted message and disseminated abstractedly over the Internet with the belief that the stego-image carrying the message would not be discovered by unauthenticated person.

We recalled all vital computational issues in the implementation of the ECGM algorithm on the one-dimensional Energized Wave equation in the paper. With these recalls, program codes were derived which gave various numerical optima controls and states. These optimal controls and states were considered as various points in thin rod as our computational problem is a one dimensional space wave problem.

The rate at which encrypted messages are being sent over the internet and other electronic means ... more The rate at which encrypted messages are being sent over the internet and other electronic means will easily capture the attention of hackers and possibly make them try to disrupt or even hack those messages so as view the original message. Steganography is designed to hide the presence of a message by hiding the secret message inside an innocent file. For effective security, steganography is sometimes combined with cryptography. In this paper, steganography and cryptography are combined to provide a robust system capable of encrypting a secret message using RSA algorithm. To hide the message, advanced LSB method is used. The original message is encrypted at the initial stage and then separated into two portions P1 and P2. An XOR operation is applied to the first portion (P1) using the odd location and to the second portion (P2) using the even position of the LSB+1.The Position of the LSB is then used to hide the XORed encrypted message. Keywords-cryptography; RSA algorithm; stegano...

The FHE is a computational algorithm that allows the computations on encrypted data; and yet, when the outputs of the computations of the encrypted data are decrypted, they still conform to the operations of the original plaintext. The Bootstrapping of the Somewhat Homomorphic Encryption Scheme (SWHE) of the Craig Gentry's PhD the- sis was studied; an algorithm that continuously reduces the inherently noisy ciphertext parameters of the Ideal Circuit at each computational iteration stage, and thus, gives more room for the less noisy ciphertext computation in the cloud based the application of addition and multiplication operations. The FHE implementation on Big Data Ana- lytcs Security on the cloud computing was discovered to have boosted confidentiali...

[Reju, 1995] was the first to apply the Extended Conjugate Gradient Method (ECGM) to the optimal control of classical wave propagation problem and with a specific extension to energized waves by [Waziri, 2006]. Computational procedures of Reju and Waziri are semi-analytic in nature utilizing in each case a direct methodology that is finally employed in the implementation of the ECGM. This paper however employs a discretization procedure via the 4 th order Runge-Kutta algorithm to the search of optimal solutions of the 2-dimensional energised wave propagation problem and so contributing to the unified theory of the foregoing diffusive and kinetic Hamiltonian approach [Reju et al, 1999] preceding the implementation of the various versions of ECGM [Reju, et al, 2001; ...

From the numerically simulated results, it was observed that the optimal values of unbounded horizon problems are obtained at the last peak of the model before shooting into non convergence state. Immediately after the optimum report is acquired, a local minimum is achieved. Thereafter, a non convergence positive result that goes into infinity is achieved. The last trough clearly gives a false positive respond. Therefore, the optimum value observed before non-convergence state should be the decisive state to quit the stage. All equipment must be constantly kept under good maintenance since the cost of maintenance increases with time. At a stage of deterioration, equipment could be refurbished and sold out at less expensive cost ...

This evolvement has led to one of the greatest challenges organizations are faced with, which is in the area of adequately protecting their sensitive information from being lost or leaked. Data Loss Prevention (DLP) techniques was created in preventing these breaches on data loss, when these breaches occur in an organization. DLP systems has gained popularity over the last decade and is now referred as a matured technology, and with the alarming rate at which digitally stored assets is growing, the need for DLP systems has also increased. This paper dis...

This is so due to increase usage of mobile phones in storage of information, law enforcement, mobile online transactions, and also negatively by criminals due to increased computational capabilities. Mobile forensics devices continue to remain a very challenging task due to poor user data retrieval techniques for evidence retrieval. Recently, third party applications assume a veritable feet because it is supported by majority of mobile devices platforms, thereby making it easy to extract information of its users' for future criminal audit. This paper proposes an evidence data retrieval method from InstagramApp using two networks-based platforms [that is, pure peer-to-peer (PPP) and special cluster peer (SCP)-based], whose concept is to manage mobile device communication and generate multiple copies of users data/information to be dumped across three servers. The forensic test results were obtained from PPP and SCP developed to securely extract data from mobile devices. This shows that, SCP outperformed PPP in terms of the time taken to fulfil forensic auditor's request, throughput and broadband utilisation which are 42.82% to 57.18%, 56.81% to 43.19% and 35.41% to 64.53% respectively.

Mobile cloud computing integrates cloud computing with mobile devices. By this architecture, certain challenges (e.g., battery life, storage, and bandwidth) of mobile devices are addressed. Cloud computing provides the foundation for mobile cloud computing through the delivery of services, software, storage and computational capacity over the Internet, thereby reducing cost, increasing storage, improving battery life of mobile devices and providing flexibility and mobility of data and information. However, the realization of some of these benefits is far from reality in mobile applications, as a result, opens new areas of research such as security of privacy and services. To better understand how to facilitate the development of mobile cloud computing, we surveyed existing work in mobile cloud computing in the context and principles of its foundational cloud computing technology. We provided a definition of mobile cloud computing and gave a summary of results from this review, in particular, the models, architecture, applications and challenges of mobile cloud computing. We concluded with recommendations for how this better understanding of mobile cloud computing can assist in the development of better and stronger mobile applications.
