Decryption is accomplished by manipulating the final state of the BBS generator using the private key, in order to find the initial seed and reconstruct the keystream. The BG cryptosystem is semantically secure based on the assumed intractability of integer factorization ; specifically, factoring a composite value N = p q {\displaystyle N=pq ...
The CM is a joint initiative to upgrade the DoD crypto inventory. Of the 1.3 million cryptographic devices in the U.S. inventory, 73 percent will be replaced over the next 10 to 15 years [when?] by ongoing and planned C4ISR systems programs, Information Technology modernization initiatives and advanced weapons platforms.

These tables compare the ability to use hardware enhanced cryptography. By using the assistance of specific hardware, the library can achieve greater speeds and/or improved security than otherwise. Smart card, SIM, HSM protocol support
In cryptography, mod n cryptanalysis is an attack applicable to block and stream ciphers. It is a form of partitioning cryptanalysis that exploits unevenness in how the cipher operates over equivalence classes (congruence classes) modulo n .
Blum Blum Shub takes the form + =, where M = pq is the product of two large primes p and q.At each step of the algorithm, some output is derived from x n+1; the output is commonly either the bit parity of x n+1 or one or more of the least significant bits of x n+1.
Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...
The ElGamal signature scheme is a digital signature scheme which is based on the difficulty of computing discrete logarithms.It was described by Taher Elgamal in 1985. [1]The ElGamal signature algorithm is rarely used in practice.
In cryptography, Galois/Counter Mode (GCM) [1] is a mode of operation for symmetric-key cryptographic block ciphers which is widely adopted for its performance. GCM throughput rates for state-of-the-art, high-speed communication channels can be achieved with inexpensive hardware resources.
