A novel reconfigurable cipher coprocessor (RCP) is designed with supporting both symmetric and asymmetric algorithms. First, a memory-sharing S-box is proposed to provide a reconfigurable S-box with reduced hardware resources. Then, arbitrary permutation unit, reconfigurable arithmetic operation unit, ...
Two popular encryption algorithms are the Advanced Encryption Standard (AES) and the Data Encryption Standard (DES) This type of encryption is typically much faster than Asymmetric Encryption, but it allows access to the secret key by both the sender and the data receiver. ...
After introducing basic cryptography concepts, this seminal textbook covers nearly all symmetric, asymmetric, and post-quantum cryptographic algorithms currently in use in applications — ranging from cloud computing and smart phones all the way to industrial systems, block chains, and cryptocurrencies. ...
Asymmetric algorithms use two different keys, one for encryption and one for decryption—a public key and a private key, respectively Whitfield Diffie and Martin Heilman first publicly released public key cryptography in 1976 as a method of exchanging keys in a secret key system. Their algorithm,...
Public key algorithms, also known as asymmetric key algorithms, are used (primarily) to solve two problems that symmetric key algorithms cannot: key distribution and nonrepudiation. The first helps solve privacy problems, and the latter helps solve authenticity problems. Public key algorithms accomplish...
Learn what asymmetric encryption is, how it works, and what it does When it comes to the word ‘Encryption,’ we think of it as a technique that protects data using a cryptographic key, and there’s nothing wrong with this. However, what most people don’t realize is that there are di...

In contexts that do not require asymmetric cryptography, such as secure data storage where the same user encrypts and decrypts data, symmetric cryptography can be used to take advantage of these benefits. Additionally, asymmetric algorithms included in OpenPGP are vulnerable to attacks that might ...
Easy-to-use, symmetric (AES-256) and asymmetric (RSA) encryption and also hash (SHA-256) library for C++ (17+) - leventkaragol/libcpp-crypto
Asymmetric encryption is far slower thansymmetric encryptionand is also weaker per bit of key length. The strength ofasymmetric encryptionis the ability to securely communicate without pre-sharing a key.Table 6.14compares symmetric andasymmetric algorithmsbased on key length. Note that systems based on...
