Three-pass protocol

노트

말뭉치

1. It is called a three-pass protocol because the sender and the receiver exchange three encrypted messages.
2. The first three-pass protocol was developed by Adi Shamir circa 1980, and is described in more detail in a later section.
3. The basic concept of the three-pass protocol is that each party has a private encryption key and a private decryption key.
4. The first three-pass protocol was the Shamir three-pass protocol developed circa in 1980.
5. In particular, the traditional Massey-Omura system is an exponential system which uses a prime modulus.
6. A stronger version of the enhanced Massey-Omura system (EMO-2) adds a digital signature to the EMO-1 system.
7. The enhanced Massey-Omura system (EMO-1) replaces the prime modulus with a composite which is the product of two distinct (large) primes.
8. The three-pass protocol uses commutative encryption to let two people communicate privately without having to exchange keys in advance.
9. The three-pass protocol is a cryptographic protocol that allows two people to communicate privately without having to exchange keys in advance.
10. The three-pass protocol does not (and generally cannot) provide authentication.
11. Introduction to ECC September 11, 2013 7 / 23 Solution 2: The three-pass protocol: Alice attaches her lock to the box and sends it to Bob.
12. The three-pass protocol: Alice attaches her lock to the box and sends it to Bob.
13. Some of the major systems based on this premise include the Diffie-Hellman key exchange system, the Massey-Omura cryptosystem, and the ElGamal cryptosystem.
14. Massey–Omura cryptosystem has some features that make it vulnerable to cryptanalysts.
15. In this research will be applied Three-Pass Protocol scheme using the Massey-Omura algorithm to secure files.
16. Therefore, it can be concluded that Massey-Omura algorithm with Three-Pass Protocol scheme in the Android platform is running well and can be implemented as an alternative for data security.
