A limitation to Cipher Block Chaining (CBC) mode, as specified in NIST Special Publication 800-38A, is that the plaintext input must consist of a sequence of blocks. Ciphertext stealing is a padding method in which the required padding bits are 'stolen' from the penultimate ciphertext block. This addendum to SP 800-38A specifies three variants of CBC mode with ciphertext stealing. These variants, which differ only in the ordering of the ciphertext bits, can encrypt any input whose. This recommendation defines five confidentiality modes of operation for use with an underlying symmetric key block cipher algorithm: Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Counter (CTR). Used with an underlying block cipher algorithm that is approved in a Federal Information Processing Standard (FIPS), these modes can provide.

  1. NIST SP 800-38A clause 5.3 says it must be, but NIST isn't the only definition of CBC. ISO/IEC 10116 also defines CBC, and explicitly excludes the derivation of IV (or SV, as they refer to it) from its scope. Clause 3.12 says: 3.12 starting variable (SV) variable possibly derived from some initialization value and used in defining the starting point of the modes of operation. NOTE The method.
  2. ARCUS for Arkime. Converts designated fields into protected formats via Elastic plug-in prior to ingesting them into index. Enables full-featured search and analytics on protected fields while retaining data-in-use protection. Data can be released to Arkime front end in clear text or masked, based on configuration
  3. complement as defined in Appendix A, NIST SP 800-38A, CS1, CS2, and CS3 are all cipher text stealing modes as defined in the Addendum to NIST SP 800-38A. CBC with CS3 is also equivalent to CTS mode in RFC 2040. The cipher text stealing modes are used a little differently in the API and have their own parameter generators. This is because they require use of both the cipher and the last two.
  4. RFC 8452 AES-GCM-SIV April 2019 for AES-GCM and can decrypt within 5% of the speed of AES-GCM (for multikilobyte messages). Encryption is, perforce, slower than AES-GCM, because two passes are required in order to achieve that nonce misuse-resistance property. However, measurements suggest that it can still run at two-thirds of the speed of AES.

PPT - Computer Security: Principles and Practice

Cipher FeedBack, defined in NIST SP 800-38A, section 6.3. It is a mode of operation which turns the block cipher into a stream cipher, with the plaintext getting XOR-ed with a keystream to obtain the ciphertext. The keystream is the last produced cipertext encrypted with the block cipher. The new() function expects the following extra parameters Test vector F.2.1 Block #1 from NIST SP 800-38A will be used, which also tells what is the correct ciphertext. A special case is when the plaintext can already be split into whole blocks. At decryption, the last byte is usually expected to be a padding byte. Therefore, a whole padding block is appended so that the last byte of the plaintext is not mistaken with the number of padding bytes.
