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...

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...
