The Tiny Encryption Algorithm
Simon J. Shepherd · Cryptologia · 2007
The Tiny Encryption Algorithm (TEA) has been around for just over ten years. It is probably the most “minimal”—and hence fastest—block cipher ever devised and yet appears resistant to most attacks. In this article, we describe the algorithm, its simplicity of design and ease of use, its cryptographic strength, and the wide range of implementations and applications of the cipher.
