Now days, Message authentication is an important security tool. B Bu ut t, , without some security mechanism, it is difficult to send data in secure manner. Most popular shortest and cheapest textual form of communication is short message service (SMS). Cryptography is the one of the main categories of computer security that converts information from its normal form into an unreadable form by using Encryption and Decryption Techniques. To ensure the security of the texts which is sent, many encryption algorithm are available. This paper will focus on message security and to secure the text data while transmitting in the network. The data which is to be transmitted from sender to receiver in the network must be encrypted using the encrypted algorithm. ). Symmetric key algorithm reduces the problem of computational overhead and to the calculation of algorithm and improves the performance of encryption. The proposed paper is to provide more efficient authentication mechanisms for textual data. The proposed review paper presents a review of security techniques for SMS and a performance comparison between most common encryption algorithms like DES, 3DES, RC4, Blowfish and AES (Rijndael)
The one thing that makes Tesla stand out from the crowd is its full automation Self-Driving feature. Not just the name itself but the technology behind it is even more interesting. It is not only about the luxury but also has a lot of advantages which backs the term. And what blows our mind is that not a lot of Indian car companies are focused on this technology on wide scale. So, inspired by that this paper presents to build a Self-Driving Autonomous car model but on minimalistic basis which basically will be focused on three main features which are to operate in accordance with the surrounding depending on the direction of the road, to detect stop sign and halt for 5-10 seconds and detect traffic signs and make decisions accordingly. The miniature self-driving car will detect the two-lane path and perform the above functions. Keywords: Autonomous Vehicles, Self-driving car, Computer Vision, Neural Network, Image processing, wireless sensor networks, control systems, path planning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
