CVE-2022-47930

An issue was discovered in IO FinNet tss-lib before 2.0.0. The parameter ssid for defining a session id is not used through the MPC implementation, which makes replaying and spoofing of messages easier. In particular, the Schnorr proof of knowledge implemented in sch.go does not utilize a session...

Insecure Session Management

github.com/iofinnet/threshlib and https://github.com/bnb-chain/tss-lib are vulnerable to Insecure Session Management. The vulnerability exists in sch.go because the implementation of the Schnorr proof of knowledge doesn't use a session id, context, or random nonce which allows a malicious user to...

SUSE CVE-2014-1692

The hashbuffer function in schnorr.c in OpenSSH through 6.4, when Makefile.inc is modified to enable the J-PAKE protocol, does not initialize certain data structures, which might allow remote attackers to cause a denial of service memory corruption or have unspecified other impact via vectors tha...

No, RSA Is Not Broken

I have been seeing this paper by cryptographer Peter Schnorr making the rounds: "Fast Factoring Integers by SVP Algorithms." It describes a new factoring method, and its abstract ends with the provocative sentence: "This destroys the RSA cryptosystem." It does not. At best, its an improvement in...

Micali-Schnorr Generator (MS-DRBG) Part III - Zero Knowledge Proof Wanted!!

See also Part I and Part II of this series This is going to be a short blog post about the infamous Micali-Schnorr Random Number Generator MS-DRBG. See Part I and Part II of this series for more information about this topic. WHO: NIST published the specification for Micali-Schnorr Random Number...
