Tunable Security Support for Wireless Applications

چکیده
A tunable and differential treatment of security is needed to achieve the best possible balance between security and performance for wireless applications. In this paper, we present a tunable encryption service that is based on a selective encryption paradigm in which applications can request a desired encryption level. Encryption levels are selected at the inception of a session, but can be changed at any time during its lifetime. In the paper, a prototype implemented on top of the Stream Control Transmission Protocol (SCTP) is described and an initial performance evaluation is presented. The results demonstrate that the proposed service offers a high degree of security adaptiveness at a low cost.

متن کاملToward an energy efficient PKC-based key management system for wireless sensor networks
Due to wireless nature and hostile environment, providing of security is a critical and vital task in wireless sensor networks (WSNs). It is known that key management is an integral part of a secure network. Unfortunately, in most of the previous methods, security is compromised in favor of reducing energy consumption. Consequently, they lack perfect resilience and are not fit for applications ...
متن کاملMiddleware Support for Tunable Encryption
To achieve an appropriate tradeoff between security and performance for wireless applications, a tunable and differential treatment of security is required. In this paper, we present a tunable encryption service designed as a middleware that is based on a selective encryption paradigm. The core component of the middleware provides block-based selective encryption. Although the selection of whic...
متن کاملDesign of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...
