The Electronic Key Management System ( EKMS) is a United States National Security Agency led program responsible for Communications Security ( COMSEC) key management, accounting, and distribution. Specifically, EKMS generates and distributes electronic key material for all NSA encryption systems whose keys are loaded using standard fill devices ...
NSA cryptography. The vast majority of the National Security Agency 's work on encryption is classified, but from time to time NSA participates in standards processes or otherwise publishes information about its cryptographic algorithms. The NSA has categorized encryption items into four product types, and algorithms into two suites.
A key management system (KMS), also known as a cryptographic key management system (CKMS) or enterprise key management system (EKMS), is an integrated approach for generating, distributing and managing cryptographic keys for devices and applications. They may cover all aspects of security - from the secure generation of keys over the secure ...
For example, Alice, Bob, and Carol could participate in a Diffie–Hellman agreement as follows, with all operations taken to be modulo p: The parties agree on the algorithm parameters p and g. The parties generate their private keys, named a, b, and c. Alice computes g a mod p and sends it to Bob. Bob computes (g a) b mod p = g ab mod p and ...
A High Assurance Internet Protocol Encryptor ( HAIPE) is a Type 1 encryption device that complies with the National Security Agency 's HAIPE IS (formerly the HAIPIS, the High Assurance Internet Protocol Interoperability Specification). The cryptography used is Suite A and Suite B, also specified by the NSA as part of the Cryptographic ...
A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on ...
Encryption is just one aspect of protecting sensitive information on such systems, and far from the most challenging aspect. NSA's role will increasingly be to provide guidance to commercial firms designing systems for government use. HAIPE solutions are examples of this type of product (e.g., KG-245A [permanent dead link] and KG-250 ).
A key encapsulation mechanism, to securely transport a secret key from a sender to a receiver, consists of three algorithms: Gen, Encap, and Decap. Circles shaded blue—the receiver's public key and the encapsulation —can be safely revealed to an adversary, while boxes shaded red—the receiver's private key and the encapsulated secret key —must be kept secret.
