A recent research paper makes the claim that the RSA cryptographic algorithm can be broken with a quantum algorithm. Skeptics warn: don’t believe everything you read. Every CISO has encryption ...

Modern encryption algorithms like RSA 2048 will remain safe from decryption by quantum computers for the foreseeable future, according to scientists from Fujitsu. The researchers used the company’s ...

One of the most well-established and disruptive uses for a future quantum computer is the ability to crack encryption. A new algorithm could significantly lower the barrier to achieving this. Despite ...

素因数分解の困難さを安全性の根拠とした暗号「RSA暗号」について、量子コンピューターを使用することで解読手法の構築 ...

There’s little doubt that some of the most important pillars of modern cryptography will tumble spectacularly once quantum computing, now in its infancy, matures sufficiently. Some experts say that ...

Public key cryptography is an encryption method that uses different keys for encryption and decryption. For example, when Bob and Alice interact, Alice creates a private key and a public key, and ...

RSA certificates still vulnerable to 2019 flaw, reaearchers say. Update, March 20, 2025: This story, originally published March 17, has been updated with a statement from RSA regarding the encryption ...

暗号化通信のための鍵を安全に交換するには「鍵交換アルゴリズム」を利用する。代表的な鍵交換アルゴリズムが「Diffie-Hellman方式」（DH法）と「RSA方式」（Rivest-Shamir-Adleman）だ。DH法およびRSA方式の違いを説明した前編「鍵交換の2大アルゴリズム『Diffie ...
