What is a block cipher in cryptography?
In cryptography, a block cipher is defined as a deterministic algorithm operating on a plaintext block along with a symmetric key and encrypts it to produce the corre- sponding cipher text. The plaintext block is a fixed-length group of bits and one block is serviced at a time unlike stream ciphers where encryption takes place bitwise.

In cryptography, a block cipher is a deterministic algorithm that operates on fixed-length groups of bits, called blocks. Block ciphers are the elementary building blocks of many cryptographic protocols. They are ubiquitous in the storage and exchange of data, where such data is secured and authenticated via encryption.

In this paper, we propose a new lightweight block cipher called LBlock. Similar to many other lightweight block ciphers, the block size of LBlock is 64-bit and the key size is 80-bit. Our security evaluation shows that LBlock can achieve enough security margin...

Apr 15, 2021 · Abstract. Block ciphers have been extremely predominant in the area of cryptography and due to the paradigm shift towards devices of resource constrained nature, lightweight block ciphers have totally influenced the field and has been a go-to option ever since.
