The Potential Attacks Against Ecdsa: A Raw Public Key Approach
Ethereum’s use of Elliptic Curve Digital Signatures (ECDSA) has made it one of the most widely adopted cryptocurrencies. However, this approach to cryptography also leaves room for potential vulnerabilities. In this article, we will explore
Why Hashed Addresses Are Secure
Before diving into the potential attempts, let’s quickly review why hashed addresses are considered secure by default in Ethereum. The Ethereum address format Hashing ensures that each address is unique and cannot be used for any transaction.
Benefits:
* Uniqueness : Each address is hashed, make it virtually impossible to reuse or compromise.
* determinism : the hash value of an address always results in the same output, reducing the likelihood of collisions.
* Non-repudiation :
Potential Attacks Against Raw Public Keys
Instead of Hashed Ones, Two Types of Attacks Could Be Possible:
Attack 1: Hash Collision
A hash collision occurs when two different inputs product of the same output. In this case,
Why it’s Possible
Hash Collisions are possible there are possible there are possible inputs (public keys) that can produce the same output (hashed value). For example:
- A public key “a” Hashing to a Specific Output.
- Another public key “B” Hashing to the same output as “a”.
- And so on.
This could lead
Attack 2: Private Key Exposure
If raw public keys are used as addresses, a private key (the secret associated with each address) may also be exposed. This is because hashing only encrypts the output, not the input. An attacker potentially obtain a copy of your private key by explicing weavnesses in your wallet or using brute force attempts.
Why it’s Possible
While hashed outputs are secure, it is possible for an attempt to get an associated This could be allow them to compromise transactions or access sensitive information about your assets.
