I have pioneered a groundbreaking method for creating ciphers that adeptly manage the encryption of large data chunks, an issue that was previously quite challenging. In the past, we faced a trade-off between efficiency and security when it came to ciphers with large block sizes. This cutting-edge approach not only offers faster performance, but is also mathematically proven to be secure against attacks that were once problematic. This makes it particularly advantageous for devices with limited computing power, such as body-implanted microchips or microprocessor cards. Consequently, these devices become more cost-effective, and the conserved resources can be allocated to additional features, ultimately boosting their overall functionality.
