Novel Performance Metric for Encryption Algorithms Used in Wireless Sensor Networks

Wireless sensor networks are vulnerable to attacks that can compromise the data transmitted through them. To ensure security and confidentiality, encryption algorithms are necessary. To evaluate the effectiveness of encryption algorithms, various metrics can be used. This paper introduces a new security metric called the sensor reading acceptance probability. This metric measures the probability that the data read by a sensor has not been compromised. To be accepted, the key strength probability must exceed a given threshold. The key strength probability is the likelihood that a cryptographic key has not been discovered by a brute force attack within a certain period of time. This metric is adaptable and can be easily used to compare the performance of different encryption algorithms.
