  • Advantages and disadvantages of Stream versus Block Ciphers
    While both are symmetric ciphers, stream ciphers are based on generating an "infinite" cryptographic keystream, and using that to encrypt one bit or byte at a time (similar to the one-time pad), whereas block ciphers work on larger chunks of data (i e blocks) at a time, often combining blocks for additional security (e g AES in CBC mode) Stream ciphers are typically faster than block, but
  • compliance - Why are CHACHA20 TLS ciphers not compliant with the NIST . . .
    Since I got an edit stating that AES-CTR, AES-OFB etc are NIST-approved stream ciphers: CTR and OFB are modes of operations for a block cipher that make it behave like a stream cipher, but I’m talking about algorithms which have been designed as stream ciphers from the beginning (like ChaCha20 or the now-obsolete RC4) The presentation I’ve linked to explains why this difference matters
  • Using AES as a Stream Cipher - Information Security Stack Exchange
    Because of this, I'm thinking I can increase throughput by using AES as a stream cipher The solution I came up with is simply to use the key to encrypt a message of all 0's with size rounded up to the nearest 128 bits, using AES and a suitable non-authenticated encryption mode like CTR
  • Can I use streaming decryption by every algorithm?
    Can you clarify what you mean by RSA "supports streaming decryption"? RSA decryption is absurdly slow (for decent key sizes) compared to symmetric algorithms for a given size of message, and works on relatively large blocks of data (based by the key size) compared to a block cipher like Rijndael AES; you would never use it to stream anything
  • How to choose a stream cipher - Information Security Stack Exchange
    Are there high-speed ciphers designed for things like internet streams without sacrificing security? There are so many options that operate in stream mode How would one choose a cipher?
  • key generation - Information Security Stack Exchange
    As Robert's comment points out, you wouldn't be able to decrypt it! Functionally, the purpose of a stream cipher is to stretch a small bit of random data (the key) to an arbitrary length (the key stream) without the losing randomness (becoming predictable) In other words, a stream cipher is a cryptographically secure pseudo-random number generator that takes the key as a seed, and produces
  • Can hash functions be used with CTR or OFB mode?
    The point of block and stream ciphers is to increase the strength of encryption protocols when data is supposed to be decrypted If you use a hash method then you can't decrypt the data as hashes are one way If you are trying to create key data rather than encrypt data then yes you could do it this way, however you're re-inventing the wheel
  • encryption - Does the terms stream and block ciphers apply to both . . .
    Stream and block ciphers are usually used with symmetric keys This is for performance reasons as public-key cryptography is much more expensive That said, public key encryption also encrypts blocks of data (block sizes in RSA are based on the key size), so it technically uses block ciphers, we just don't usually focus on that In short, it's more about the cost of encryption decryption than
  • What are some examples of a block ciphers versatility over a stream . . .
    Most stream ciphers are blocks ciphers with some sort of operation mode being used to tweak the encryption of the "next" block Frequently data from the previous block is used to alter the output of the "next" block, which to your second question, will make it impossible to decrypt the next block if you loose the previous one For example, in a network transmission it is quite possible you'll
  • cryptography - How are ciphers related to cryptographic algorithms like . . .
    A cipher is a cryptographic algorithm Stream ciphers generate keystream by x-oring the plaintext to encrypt They are very fast compared to block ciphers A benchmark comparison can be seen at WolfSSL website, compare AES-128 vs ChaCha Block ciphers operate on blocks as Advanced Encryption Standard (AES) is 128-bit block-size AES is one of the Block ciphers as the current standard by NIST
