(vi) Lastly, the requester A applies a publicly known hash function [h.sub.2](.) as (19) to the encrypted message [bar.C] to create a unique message digest m after obtaining the sequence of ciphertext blocks [C.sub.i].
Notably, the players must submit their identities (including the players' name, email, and addresses) and a random number to PKG and then PKG signs the message digest of the identity by its [d.sub.PKG] and [d.sub.PKG].
MR checks the message digest (H([E.sub.G]([M.sub.2]) [parallel] [MAC.sub.LAAA1])) to detect the message modification attack, uses G key to decrypt the encrypted message to obtain [R.sub.1], [R.sub.2], K and [Z.sub.service] and checks the random number R1 for avoiding the replay attack.
For the corporate office to send a message that meets all four encryption objectives, a message digest must first be calculated.
Support is included for 3DES and digital signatures using Hashed Message Authentication Codes Message Digest (HMACMD5) and Secure Hashing Algorithm (HMA SHA-l).
Use secure message digest. For security of credit card numbers, use the secure hashing algorithm (known as SHA-1) to make a unique surrogate value that can be referenced, but not used to charge against the account.
* Having composed her message, Alice then uses the "hash function" of her encryption software to produce a "message digest" of the message.
Built into each of the four ports of the MultiFlow 5000's plug-in V.35 module, the IPSec support includes Triple DES (data encryption standard) encryption, MD5 (message digest 5) message authentication, and IKE internet key exchange).
To send a secure email using ViaCode, a sender first creates a digital signature by running a source document through an algorithm to produce a "message digest", which is then encrypted with the sender's private key.
A hash function takes a digital stream of bits and converts it to a fixed-length byte or bytes known as a "hash-value," a "hash," or, in information-security guidelines, a "message digest." You can think of it as an electronic abbreviation of the document transmitted, kind of like a document head-note-in-bits.
This field would contain a message digest for the header and another for the body of the email.
It also includes a general-purpose cryptographic library, with implementations of the industry's best-regarded algorithms such as 3DES (Triple DES), AES, and RSA as well as message digest algorithms and message authentication codes.
