Implementation of AES-GCM encryption algorithm for high Many of the AES-GCM applications are power and resource constrained and requires efficient hardware implementations. In this project, AES-GCM algorithms are evaluated and optimized to identify the high-performance and low-power architectures. The Advanced Encryption Standard (AES) is a specification for the encryption of electronic data. Galois/Counter Mode (GCM) GCM provides confidentiality and authenticity for the encrypted data and authenticity for the additional authenticated data (AAD). The AAD is not encrypted. GCM mode requires that the IV is a nonce, i.e., the IV must be unique for each execution of the mode under the given key. The steps for GCM encryption are:

How to Encrypt/Decrypt files and byte arrays in Java using

Since you cannot parallelize CBC encryption, a multithreaded implementation of GCM encryption (especially with PCLMUL) should be significantly faster. It pretty much gets the speed advantages of CTR if the CPU has PCLMUL. – forest Apr 24 '18 at 7:23 AES-GCM authenticated encryption - CryptoSys
