Suite B cryptography secures information traveling over networks using four well established, public-domain cryptographic algorithms:
Answer:
•Encryption using the AES with128- or 256-bit keys in the GCM mode. The block cipher modes of operation include CTR mode and GCM mode, in which case, GCM is the most common. GCM is an authenticated encryption algorithm that is designed to provide both data authenticity and confidentiality.
•Digital signatures using the ECDSA with 256 and 384-bit prime moduli.
•Key agreement using the ECDH method.
•Message digest using the SHA-2 method (SHA-256 and SHA-384).
