Modern business information technologies, such as Cloud computing and Bring Your Own Device (BYOD) raise new requirements for end node security. Cryptographic algorithms must be used to ensure security of business data and communications. However, data encryption decreases battery lifetime on mobile devices such as smartphones or tablet PCs. In this paper, we provide an analysis of energy consumption characteristics of cryptographic algorithms from Bouncy Castle Crypto API. We propose a cryptography-oriented energy-security trade-off model and use it to evaluate energy-efficiency of cryptographic algorithms.
