Comparison of sequence cipher and block cipher

The block cipher has a certain size as the base unit for each processing, while the sequence cipher is an element (a letter or aBITS) as a basic processing unit. A sequence cipher is an encrypted transformation that changes over time and has a conversion speedThe advantages of fast and low error propagation, the hardware implementation of the circuit is more simp

But do we associate the method's overwrite? method is not accessible through this method (unless the parent class method is called using the Super keyword in a subclass method). Because after coercion of type conversion, although the father's reference is still an instance of the subclass, the method called is also a subclass of the method

Symmetric encryption algorithm and pattern of block cipher

This is a creation in Article, where the information may have evolved or changed. Symmetric encryption algorithms, that is, encryption and decryption using the same cryptographic key encryption and decryption algorithm. Block cipher is a class of encryption and decryption algorithms that can handle only a block of data of a specific length at a time. At present, the symmetric encryption Algorithm DES, 3DES, AES belong to the block

Block cipher mode: OFB mode (output feedback mode)

In the OFB mode, the output of the cryptographic algorithm is fed back into the input of the cryptographic algorithm, and the OFB pattern is not directly encrypted by the cipher algorithm, but by XOR the output of the plaintext packet and cipher algorithm to create the ciphertext grouping, at which point the OFB mode and the CFB mode are very similar, as shown in:The difference between the OFB mode and the
