RSA DIGITAL SIGNATURES A digital signature is used to prove the identity of the sender of a message and to show that a message has not been tampered with since the sender posted it. This provides authentication, integrity, and non-repudiation. To create a digital signature using RSA encryption, the private key is used to encrypt the signature; the public key is distributed to allow others to read it. I think answer is b.RSA.

Guys/Gals , RSA Is used for encryption not integrity , integrity = hashing = MD5 Encryption = Confidentiality RSA is widely used for key exchange, encryption, and digital signatures

Integrity = hashing, RSA is asymmetric algorithm Experts discovered significant vulnerabilities in MD5 in 2004 and later years Security experts now consider it cracked and discourage its use. However, it is still widely used to verify the integrity of files. "DARRYL GIBSONs Book"

Non-repudiaton=Digital Signature, digital signature uses asymmetric cryptography to achieve integrity, authentication and non-repudiation. B. RSA

Hash values are also useful for verifying the INTEGRITY of data sent through insecure channels. So MD5 and SHA hash is ruled out. Non-repudiation = digital signatures, RSA provides that

It’s RSA a two second google search proves this

Providing end-to-end file non-repudiation requires using a secure file transfer server that can perform file integrity checking, The cryptographically valid SHA1 and MD5 algorithms are widely used to do file integrity checking. SHA1 is the stronger of these, and is approved for file integrity checking since SHA1 is not one of the option, the next best is MD5 - (C)

KEY “file transmission”. It’s MD5

jason dion in his notes. Digital signature use either DSA,RSA,ECDSA, or SHA. To prevent spoofing of a message integrity. I am thinking it is RSA

we are talking about non repudiation for a file transferring means the file integrity MD5 is correct

answer is RSA. As the answer can't be MD5, MD5 isn't as secure as SHA, if it was purely a hashing algorithm the chosen answer would have been SHA not MD5

Non-repudiation is the ability to prove that the file uploaded and the file downloaded are identical. The cryptographically valid SHA1 and MD5 algorithms are widely used to do file integrity checking. MD5 makes sense here.

RSA -> Digital Signatures -> non-repudiation

They specifically ask abt fie transmission , check this https://www.ipswitch.com/resources/best-practices/file-non-repudiation

should be B RSA is the most widely used asymmetric algorithm: It provides a method to assure the confidentiality, integrity, authenticity, and non-repudiation of electronic communications and data storage.

If you read this, you will be lead to see C. MD5 is correct, since SHA (aka SHA-1) has been shunned from service? Non-repudiation Techniques: For email transmission, non-repudiation typically involves using methods designed to ensure that a sender can’t deny having sent a particular message, or that a message recipient can’t deny having received it. Techniques would include email tracking. Cryptographic hash functions may be used to establish the integrity of transmitted documents. No encryption keys are involved, and strong hash functions are designed to be irreversible. Moreover, they’re designed to avoid collision, which occurs in the rare cases where two separate documents give rise to the same hash value.

wife...how comptia keep its non-repudiation?
