In this paper we seek for a more flexible, yet secure, GPAKE and put forward the notion of partitioned GPAKE. Partitioned GPAKE tolerates users that run the protocol on different passwords. Through a protocol run, any subgroup of users that indeed share a password, establish a session key, factoring out the ``noise'' of inputs by users holding different passwords.

Computational Complexity and the Anthropic Principle
"Namely, if suicide really were a solution to life's problems, then one could exploit that fact to solve NP-complete problems in polynomial time! I'm thinking of starting a suicide hotline for computer scientists, where I'll explain this point to them."

SafeDeflate
Abstract: CRIME and BREACH attacks on TLS/SSL leverage the fact that compression ratio is not hidden by encryption to recover content of secrets. We introduce SafeDeflate---a modification of a standard Deflate algorithm which compression ratio does not leak information about secret tokens. The modification is compatible with existing Deflate and gzip decompressors. We introduce a model in which attacker can obtain ciphertexts of arbitrary compressed plaintext containing secret values. Then we prove that SafeDeflate is secure in this model.
