What is the block size used by the Present encryption algorithm?

The Present encryption algorithm uses a block size of 64 bits. This means that the algorithm processes data in blocks of 64 bits at a time during encryption and decryption. Present is notable in the field of lightweight cryptography, designed specifically for resource-constrained environments, such as RFID tags and sensor networks. Using a 64-bit block size helps maintain a balance between security and efficiency in such constrained environments, making it suitable for applications where processing power and memory are limited.
