Subject: aes-ctr vs aes-cbc We've been trying to migrate our ssh/sftp environment, for both our client and server users to only use FIPS-140-2 certified ciphers, and run ICSF in FIPS mode. We've had no problems doing so, except with one of our partners who states that their security policy will not allow their sftp server to accept data transmitted with any CBC cipher.

While not "incorrect" Steven's answer is incomplete. The linked article is a very good description for how to enable and disable cipher suites like SSL 2.0 etc, but SH's pen test comments posted are also concerned about the mode of operation of the ciphers used - specifically about removing the use of CBC (Cipher Block Chaining) and using Counter (CTR) or Galois Counter (GCM).

The CBC mode of operation incurs pipeline stalls that hamper its efficiency and performance. Like in CTR, blocks are numbered sequentially, and then this block number is combined with an IV and encrypted with a block cipher E, usually AES. The result of this encryption is then XORed with the plaintext to produce the ciphertext. 2019-02-04 · AES-CBC vs AES-GCM. Until recently the only AES cipher that you were likely to encounter in the VPN world was AES-CBC (Cipher Block Chaining).

When encrypting table space pages (such as pages in InnoDB, XtraDB, and Aria tables), you use AES in Counter (CTR) mode. Authenticated encryption schemes (with associated data (AEAD)) combine the two part process of encryption and authentication into one block cipher mode that also produces an authentication tag in the process. In most cases this results in speed improvement. CCM is a simple combination of CTR mode and a CBC-MAC. AES CBC or AES CTR mode In symmetric encryption sometimes it's hard to decide which mode to use. Especially between AES CBC mode and AES CTR (Counter) mode. Here are some pro and cons of these two modes: 2019-08-08 · Or we can use the mode of AES which support a stream of plaintext, like CFB, OFB, CTR mode.

They will both work, but CTR easier to encode and cleaner (3)CTR can be encoded in parallel (4)CBC requires an extra block to be transferred whenever a skip is made (5)CTR mode has been considered better, but there were concerns about security. These have been fixed and moving forward, CTR is the trend The main idea behind the block cipher modes (like CBC, CFB, OFB, CTR, EAX, CCM and GCM) is to repeatedly apply a cipher's single-block encryption / decryption to securely encrypt / decrypt amounts of data larger than a block.. Some block modes (like CBC) require the input to be split into blocks and the final block to be padded to the block size using a padding algorithm (e.g. add a special 2019-01-25 • Unlike OCB, AES CTR and CBC-MAC require only encryption operations, not decryption • Software: CTR with CBC-MAC is smaller – Cut table size in half (4K bytes vs.

Both AES counter mode (CTR) and Cipher Block Chaining (CBC) are specified in separate protection schemes. Partial encryption using a pattern of encrypted

But in general you are right; CBC is an older mode that was invented back in the dark ages cryptographically speaking (no later than the 1970s), and is now disfavored because of the lack of built-in authentication and all the trouble that's been caused by padding oracles. The Advanced Encryption Standard (AES),- is a block cipher adopted as an encryption standard by the U.S. government for military and government use. ECB (Electronic Codebook) - is essentially the first generation of the AES. It is the most basic form of block cipher encryption. AES-CBC is an encryption algorithm, whereas SHA is a hashing algorithm, they are seperate algorithms. AES-GCM algorithm performs both encryption and hashing functions without requiring a seperate hashing algorithm, it is the latest Suite B Next Generation algorithm and probably not supported on as ASA 5505.
