Newly Discovered Factorization Attack in Cryptographic library that is used for generation RSA Key allows Attacker to compute Millions of cryptographic smartcards, security tokens, and Motherboard Chipsets Private key by having a target’s public key.
The Public and Private key pair comprised of two uniquely related cryptographic keys.The Public Key is what its name suggests – Public. It is made available to everyone via a publicly accessible repository or directory. On the other hand, the Private Key must remain confidential to its respective owner.
This Serious security Flow Discovered in cryptographic smartcards, security tokens that are Manufactured by Infineon Technologies AG and also integrated into authentication, signature and encryption tokens of other vendors and chips used for Trusted Boot of operating system.
Factorization Attack in this Cryptographic library allows to impersonate key owners, decrypt sensitive data , bypass the Protected PCs by Attackers.

These Encryption key used in some of high-security Standard Platforms such as national identity cards, software- and application-signing, and trusted platform modules protecting government and corporate computers.
According to Researchers ,The Public Key is what its name suggests – Public. It is made available to everyone via a publicly accessible repository or directory. On the other hand, the Private Key must remain confidential to its respective owner.
In this Case No Physical access to Vulnerable Devices is required and Public Key is Enough to Compute the Private key of Vulnerable Smartcards,Security tokens and Mother Board Chipset.
This Flow not Depends on a fault in random number generator but all RSA keys generated by a vulnerable chip are impacted.
