What is the IV value used for the stream cipher Enocoro?

The Initialization Vector (IV) value for the stream cipher Enocoro is 64 bits. In stream ciphers, the IV is crucial as it ensures that the same plaintext encrypted multiple times will yield different ciphertexts, enhancing security against certain types of attacks, such as replay attacks or known-plaintext attacks. By using a 64-bit IV, Enocoro provides a balance between security and efficiency. A larger IV size could provide better security against collision attacks but would also require more computational resources and might slow down the encryption process. Therefore, the selection of a 64-bit IV aligns with the design goals of providing robust cryptographic security while maintaining performance efficiency.
