It is therefore vulnerable to attackers, and attackers can use false nodes or MAC injection attacks through the hijacked nodes to reduce the lifetime of the network or trigger false alarms. In order to prevent such attacks, several security protocols have been proposed, and all of them have been subjected to MAC-dependent validation, making it impossible to defend against false report attacks in extreme attack circumstances.

As attacks have recently become more diverse and more intelligent, WSNs require intelligent methods of security. Based on the report information gathered from the base station, the proposed method provides a technique to prevent attacks that may occur where all MAC information is damaged by carrying out verification of a false report attack through the machine learning based prediction model and the evaluation function.

This being named as Opportunistic Vehicular Edge Computing recently, has the possibility to supplement the services provided by the Edge gadgets. Many Vehicular Edge Computing architectures have been proposed as of late which support task offloading.

One among the premier difficulties in these networks is efficiently utilizing the resources available at the vehicular nodes. The present work uses APEATOVC, a conveyed and versatile protocol for economical, efficient and effective task offloading in these networks which address the adaptability of vehicular clouds.

The results obtained by extensive simulations are presented to assess and contrast its performance with existing protocols. Loke, and Wenny Rahayu. A survey. Hassanein, and Glen Takahara.

Springer, Cham, Springer, New York, NY, The main problem with these systems is the high service delay where the mobile clients have to wait to view their favorite movie. The importance of this paper is based on finding a solution on how to reduce the delay time in the VOD system.

This paper introduces a novel caching mechanism named Proxy Server Cache mechanism to tackle the issue of service delay. This delay happens when the broadcasting phase that is related to the first segment is missed by a client from the current broadcasting channels. The delayed clients will directly acquire the first segment from the proxy server instead of waiting for the following broadcasting channel pertaining to the first segment.

The proposed scheme ensuresobtaining the first segment from mobile clients when they arrive. Additionally, the performance of the proposed scheme is validated by applying the VOD system, which can involve the balancing mechanism to retain particular requests through to the local proxy server to provide a fair dissemination for these requests. The obtained result confirms that the proposed scheme reduces the time delay of the system in comparison with the best existing schemes.

The results of the average time delay in the Proxy-Cache scheme is Meanwhile, the failure probability for obtaining the first segment of the video remains zero when the number of arrived requests is set to2, 4, 6, 8 and Protocol considerations for a pre-caching proxy for multimedia streams, in Proc.

Security in terms of confidentiality, integrity, authentication, authorization, and availability. Key management is one of the major constraints for resource constraint mobile sensor devices.

This work is an extension of the work done by Kumar et al. This work ensures cryptographic property, availability, in RFID-WSN integrated network through outlier detection mechanism for 50 to nodes network. Through detection ratios and anomaly scores system is tested against outliers. The proposed outlier detection mechanism identifies the inliers and outliers through anomaly score for protection against Denial-of-Service DoS attack.

Intruders can be detected in few milliseconds without giving any conflict to the access rights. In terms of throughput, a minimum improvement of 6.


Kumar, K. Gopal and A. They are the modes of operation and must be carefully considered when using a block cipher in a cryptosystem. Despite its deprecation as an official standard, DES especially its still- approved and much more secure triple-DES variant remains quite popular; it is used across a wide range of applications, from ATM encryption to e-mail privacy and secure remote access.

Many other block ciphers have been designed and released, with considerable variation in quality. Many have been thoroughly broken. Public-key cryptography Symmetric-key cryptosystems use the same key for encryption and decryption of a message, though a message or group of messages may have a different key than others.

A significant disadvantage of symmetric ciphers is the key management necessary to use them securely. Each distinct pair of communicating parties must, ideally, share a different key, and perhaps each ciphertext exchanged as well.

The number of keys required increases as the square of the number of network members, which very quickly requires complex key management schemes to keep them all straight and secret.

The difficulty of securely establishing a secret key between two communicating parties, when a secure channel doesn't already exist between them, also presents a chicken-and-egg problem which is a considerable practical obstacle for cryptography users in the real world.

In a groundbreaking paper, Whitfield Diffie and Martin Hellman proposed the notion of public-key also, more generally, called asymmetric key cryptography in which two different but mathematically related keys are used — a public key and a private key.

A public key system is so constructed that calculation of one key the 'private key' is computationally infeasible from the other the 'public key' , even though they are necessarily related. Instead, both keys are generated secretly, as an interrelated pair. In public-key cryptosystems, the public key may be freely distributed, while its paired private key must remain secret.

The public key is typically used for encryption, while the private or secret key is used for decryption. In addition to encryption, public-key cryptography can be used to implement digital signature schemes.

A digital signature is reminiscent of an ordinary signature; they both have the characteristic that they are easy for a user to produce, but difficult for anyone else to forge.

Digital signatures can also be permanently tied to the content of the message being signed; they cannot then be 'moved' from one document to another, for any attempt will be detectable. In digital signature schemes, there are two algorithms: one for signing, in which a secret key is used to process the message or a hash of the message, or both , and one for verification, in which the matching public key is used with the message to check the validity of the signature.

Public-key algorithms are most often based on the computational complexity of "hard" problems, often from number theory. For example, the hardness of RSA is related to the integer factorization problem. More recently, elliptic curve cryptography has developed in which security is based on number theoretic problems involving elliptic curves.
