For these reasons, as soon as cryptography is included in a project, it is important to choose encryption algorithms that are considered strong and secure by the cryptography community. What is the potential impact? The cleartext of an encrypted message might be recoverable. Additionally, it might...
The receiver detects the radio transmission and checks the device address to see if it is part of the network. If so, it retrieves the corresponding secret symmetrical encryption key from a table and decodes the message. Comparing the decrypted address and control data with the corresponding pla...
Modern high-level encryption methods rely on mathematical processes that are relatively simple to create, but extremely difficult to decipher.Public-key encryptionis a good example. It uses two keys -- one for encoding a message and another for decoding. The encoding key is the public key, avai...
If so, check that you use Rijndael (now referred to as Advanced Encryption Standard [AES]) or Triple Data Encryption Standard (3DES) when encrypted data needs to be persisted for long periods of time. Use the weaker (but quicker) RC2 and DES algorithms only to encrypt data that has a sh...

A strong MAC must be resistant to this type of attack. A chosen plaintext attack is a type of attack wherein an attacker creates a new valid message-tag pair they can use without knowing the key required to generate it. Basically, they’re attacking your encryption function. Let’s ...
For this reason, the first block requires an initialization vector (IV), also called a "starting variable" (SV). If the same IV is used for multiple encryption sessions or messages, each new encryption of the same plaintext input would always produce the same ciphertext output. This may ...
This article may help you implement very strong cross platform encryption / decryption. The sample code is in C++, C# and Java. However, Java through JNI (Java Native Interface) and C# through COM, can call native C++ code, which in my testing appears to be much faster as compared to pu...
Therefore, this paper introduces Hybrid Encryption Algorithms (HEA) by combining symmetric key (Message Authentication Code [MAC]) and asymmetric key cryptographic techniques (Modified and Enhanced Lattice銆 sed Cryptography [MELBC]) are used to provide strong security, because symmetric techniques ...
