SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In information security, message authentication or data origin authentication is a property that a message has not been modified while in transit (data integrity) and that the receiving party can verify the source of the message. Message authentication does not necessarily include the property of non-repudiation. Message authentication is typically achieved by using message authentication codes (MACs), authenticated encryption (AE) or digital signatures. Some cryptographers distinguish between "message authentication without secrecy" systems -- which allow the intended receiver to verify the source of the message, but don't bother hiding the plaintext contents of the message -- from authenticated encryption systems. A few cryptographers have researched subliminal channel systems that send messages that appear to use a "message authentication without secrecy" system, but in fact also transmit a secret message.

In cryptography, a message authentication code (MAC), sometimes known as a tag, is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed. The MAC value protects both a message's data integrity as well as its authenticity, by allowing verifiers (who also possess the secret key) to detect any changes to the message content.

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Non-repudiation refers to a state of affairs where the author of a statement will not be able to successfully challenge the authorship of the statement or validity of an associated contract. The term is often seen in a legal setting wherein the authenticity of a signature is being challenged. In such an instance, the authenticity is being "repudiated". In a general sense non-repudiation involves associating actions or changes to a unique individual. For a secure area, for example, it may be desirable to implement a key card access system. Non-repudiation would be violated if it were not also a strictly enforced policy to prohibit sharing of the key cards and to immediately report lost or stolen cards. Otherwise determining who performed the action of opening the door cannot be trivially determined. Similarly, for computer accounts, the individual owner of the account must not allow others to use that account, especially, for instance, by giving away their account's password, and a policy should be implemented to enforce this. This prevents the owner of the account from denying actions performed by the account. Regarding digital security, the cryptological meaning and application of non-repudiation shifts to mean: A service that provides proof of the integrity and origin of data. An authentication that can be asserted to be genuine with high assurance. Proof of data integrity is typically the easiest of these requirements to accomplish. A data hash, such as SHA2, is usually sufficient to establish that the likelihood of data being undetectably changed is extremely low. Even with this safeguard, it is still possible to tamper with data in transit, either through a man-in-the-middle attack or phishing. Due to this flaw, data integrity is best asserted when the recipient already possesses the necessary verification information. The most common method of asserting the digital origin of data is through digital certificates, a form of public key infrastructure to which digital signatures belong. Note that the public key scheme is not used for encryption in this form; i.e. the goal is not to achieve confidentiality, since a message signed with a private key can be read by anyone using the public key. Verifying the digital origin means that the certified/signed data can be, with reasonable certainty, trusted to be from somebody who possesses the private key corresponding to the signing certificate. If the key is not properly safeguarded by the original owner, digital forgery can become a major concern. The ways in which a party may attempt to repudiate a signature present a challenge to the trustworthiness of the signatures themselves. The standard approach to mitigating these risks is to involve a trusted third party. The two most common TTPs are forensic analysts and notaries. A forensic analyst specializing in handwriting can look at a signature, compare it to a known valid signature, and make a reasonable assessment of the legitimacy of the first signature. A notary provides a witness whose job is to verify the identity of an individual by checking other credentials and affixing their certification that the party signing is who they claim to be. Further, a notary provides the extra benefit of maintaining independent logs of their transactions, complete with the type of credential checked and another signature that can independently be verified by the preceding forensic analyst. For this double security, notaries are the preferred form of verification. On the digital side, the only TTP is the repository for public key certificates. This provides the recipient with the ability to verify the origin of an item even if no direct exchange of the public information has ever been made. The digital signature, however, is forensically identical in both legitimate and forged uses - if someone possesses the private key they can create a "real" signature. The protection of the private key is the idea behind the United States Department of Defense's Common Access Card (CAC), which never allows the key to leave the card and therefore necessitates the possession of the card in addition to the personal identification number (PIN) code necessary to unlock the card for permission to use it for encryption and digital signatures.

How to achieve integrity and authenticity with Message Authentication Code MAC ?
 
03:17
The protocol for generating and verifying a message authentication code MAC is based on a secret key k shared by the sender and the recipient and is performed using a cryptographic algorithm A. The sender sends not only the bare message m, but follows the message with its corresponding message authentication code MAC. The MAC is computed from the common algorithm A with the secret key k, as follows: MAC=A_k(m) The system does not prevent Mr. X from altering the original message m and its MAC to the new message m' and its corresponding message authentication code MAC'. Now it is the recipient's turn to act. He very much wants to know whether the message received is the one that was sent. In order to check this, he simulates the sender's procedure. He applies the algorithm A with key k to the received message m' and verifies whether the result coincides with the received message authentication code MAC'. If A_k(m') is not equal to MAC', then the recipient knows for certain that something has happened ! and he consequently does not trust the message and reject it. If, however, A_k(m') is equal to MAC' then he reasonably certain that the message was not changed. Of course, this certainty relies heavily on the strength of the cryptographic algorithm A and the number of possible keys. Let us keep in mind the underlying philosophy: Mr. X's deception is foiled since he must find the corresponding message authentication code MAC for his message m', which he cannot do because he does not know the secret key k. The mechanism of the MAC is a tool for achieving message integrity and message authenticity. If the verification works, then the recipient also know that the message is authentic because the sender is the only other person who knows the secret key k.

https://8gwifi.org/hmacgen.jsp The Keyed-Hash Message Authentication Code HMAC tutorial FIPS PUB 198-1 The purpose of a MAC is to authenticate both the source of a message and its integrity without the use of any additional mechanisms. HMACs have two functionally distinct parameters, a message input and a secret key known only to the message originator and intended receiver(s). Additional applications of keyed-hash functions include their use in challenge-response identification protocols for computing responses, which are a function of both a secret key and a challenge message. Cryptographic key (key): a parameter used in conjunction with a cryptographic algorithm that determines the specific operation of that algorithm. In this Standard, the cryptographic key is used by the HMAC algorithm to produce a MAC on the data. Hash function: a mathematical function that maps a string of arbitrary length (up to a pre- determined maximum size) to a fixed length string. Keyed-hash message authentication code (HMAC): a message authentication code that uses a cryptographic key in conjunction with a hash function. Message Authentication Code (MAC): a cryptographic checksum that results from passing data through a message authentication algorithm. In this Standard, the message authentication algorithm is called HMAC, while the result of applying HMAC is called the MAC.
