Evidence for the Security of PKCS #1 Digital Signatures

This is interesting research: "On the Security of the PKCS1 v1.5 Signature Scheme": Abstract: The RSA PKCS1 v1.5 signature algorithm is the most widely used digital signature scheme in practice. Its two main strengths are its extreme simplicity, which makes it very easy to implement, and that...

openSUSE Security Update : bouncycastle (openSUSE-2018-1043)

This update for bouncycastle fixes the following security issue : - CVE-2018-1000180: Fixed flaw in the Low-level interface to RSA key pair generator. RSA Key Pairs generated in low-level API with added certainty may had less M-R tests than expected bsc1096291. %NASLMINLEVEL 70300 C Tenable Netwo...

Debian DSA-4305-1 : strongswan - security update

Sze Yiu Chau and his team from Purdue University and The University of Iowa found several issues in the gmp plugin for strongSwan, an IKE/IPsec suite. Problems in the parsing and verification of RSA signatures could lead to a Bleichenbacher-style low-exponent signature forgery in certificates and...

New Findings About Prime Number Distribution Almost Certainly Irrelevant to Cryptography

Lots of people are e-mailing me about this new result on the distribution of prime numbers. While interesting, it has nothing to do with cryptography. Cryptographers aren't interested in how to find prime numbers, or even in the distribution of prime numbers. Public-key cryptography algorithms li...

Updated bouncycastle packages fix security vulnerabilities

Updated bouncycastle packages fix security vulnerabilities: Ensure full validation of ASN.1 encoding of signature on verification. It was possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may have allowed the introduction of...
