WebMar 15, 2024 · I received a requirement to implement encryption with AES-CTR with a 128-bit key and 128-bit IV. ... "So using the nonce and the counter exactly the same way is crucial, right?". Yes, of course. AES-CTR, regardless of the key size, uses a 128-bit block size and that is always the size of the initial counter block. Web, CTR-mode encryption enables effective utilization of the above features. For many ciphers, a well-optimized implementation of CTR-mode encryption on a processor such as an Pentium III, Itanium, Alpha, or a Motorola AltiVec, may be substantially faster (even more than four times [8]) than a well-optimized implementation of CBC-mode encryption.
