Compromised TLS Certificates
Indian CA eMudhra issued eight TLS certificates with catastrophically weak P-384 private keys, raising fundamental questions about CA audit effectiveness and the reliability of the WebPKI trust model.
Summary written by editorial AI · Source link below
The Indian CA eMudhra Limited has eight TLS certificates with laughably weak private keys : The compromised eMudhra keys were defective at a level that’s challenging the imagination of many of the engineers studying the incident. A normal size for a NIST P-384 elliptic curve cryptography private key contains roughly 384 bits of entropy, a size allowing almost 2 384 , or a number with 116 digits, different possibilities. The private key sizes of the compromised keys ranged from 3 to 8 bits. Aston
Editorial Analysis
Framed for the Security Researcher desk
NIST P-384 keys so weak they challenge engineering imagination represent a cryptographic failure worth investigating — whether due to faulty RNG, implementation bug, or deeper systemic issue.
Investigate the root cause of the weak key generation and publish findings to improve CA auditing standards and tooling.
A certificate authority issued TLS certificates with effectively broken cryptography, threatening the trust model that secures internet communications.
