Encryption algorithms take the original message, or plaintext, and convert it into ciphertext, which is not understandable. The key allows...

Cryptography in the cloud employs encryption techniques to secure data that will be used or stored in the cloud. It...

Cryptographic Key Management (CKM) is a fundamental part of cryptographic technology and is considered one of the most difficult aspects...

This is a simple substitution cipher which operates on single bits and bytes, instead of on letters.

Substitution ciphers are about replacing each group of plaintext letters with another predefined group. For decrypting, one should use a...

After the RSA algorithm was published, Diffie and Hellman came up with their own algorithm. Diffie-Hellman is used for secret-key...

Digital Signature Algorithm (DSA): The algorithm specified in NIST's Digital Signature Standard (DSS), provides digital signature capability for the authentication of messages.

The Caesar cipher is a simple substitution cipher, which replaces each plaintext letter with a different letter of the alphabet....

Public Key Cryptography, or asymmetric cryptography, uses two keys to encrypt data. One is used for encryption, while the other...

Secret Key Cryptography, or symmetric cryptography, uses a single key to encrypt data. Both encryption and decryption in symmetric cryptography...
