Is a hash-based signature a good choice for cryptography?
The current development toward quantum attack has shocked our confidence on classical digital signature schemes. As one of the mainstreams of post quantum cryptography primitives, hash-based signature has attracted more and more concern in both cryptographic research and application in recent years.
What are the different types of digital signature attacks?
As the digital signature provides authenticity and non-repudiation in order to secure important data, it is very much susceptible to various attacks. 1. Chosen-message Attack 2. Known-message Attack 3. Key-only Attack Let us consider an example where c is the attacker and A is the victim whose message and signature are under attack. 1.
Can digital signatures be hacked?
Moreover, an intensive survey and classification of 117 attacks has been done, supporting the correctness and exhaustiveness of our taxonomy. The results obtained from the survey suggest that there is an array of methods an attacker can employ to subvert the security of digital signatures.
Is a digital signature vulnerable to a man-in-the-middle attack?
The private key used in the digital signature is confidential; if attackers find it by using various techniques, then this can result in an attack. This paper presents a brief introduction about the digital signature and how it is vulnerable to a man-in-the-middle attack.
