Mobile Computing devices are increasing enormously in all fields of communication, which aims to focus on secure transfer of information. In order to provide authentication, message integrity and secure message transfer, developers need to access the cryptographic packages. The objective of this paper is to analyze and compare various algorithms discussed in Bouncy Castle Toolkit. Analysis was performed...
Due to rapid advance of the RFID systems, there is sufficient computing power to implement the encryption and decryption required for the authentication during transactions nowadays. In addition, RFID tags have enough capacity to store the corresponding information. Therefore, RFID enabled credit card can be used to improve the potential security issues occurred while using the traditional credit...
It is fair to say that most, if not all, VANET applications rely on accurate location information. It is therefore imperative to provide mechanisms that ensure the integrity, availability, and confidentiality of location information. In this article we present a number of location security mechanisms specifically designed for VANETs. Proposed mechanisms for location integrity range from the use of...
Threshold cryptography distributes the ability to provide a cryptographic service such as decryption or signing. It is an ideal choice to provide security services, such as authentication and access control, in MANETs or P2P systems. The paper proposes an ID- based threshold signature scheme, which has three attractive properties: (1) The user's co-signing key and signature share are all verifiable,...
In this paper, we introduce a secure mobile payment model suitable for macro transactions that compromise cost, simplicity, security, and performance of transaction, with minimum number of cryptography key usages, and less encryption/decryption operations compared to other models. This model can use symmetric and asymmetric cryptography without the need of trusted 3rd parties or even PKI complexity...
