 as far as i can understand it, Galois Counter Mode (GCM) which is very popular, despite having repetition after 4gb is a variant of straight Counter Mode (CTR), and then you can add on AEAD which is some bullshit that gives you some kind of hash based signature that "authenticates" the data (via some random new key, usually, sent at the beginning of a transmission or so) and note that when i say "transmission error" with the case of feedback ciphers, where the ciphertext of a block is hashed to generate the next ciphertext, this only applies within the context of a transmission unit, ie, about 1500 bytes or so... so if your data stream has its own error correction then a dropped packet is the same as a mangled packet so long as there is a stream sequence number
