An Architecture for Distributed Dictionary Attacks to OpenPGP Secret Keyrings
نویسندگان
چکیده
We describe a distributed computing platform to lead large scale dictionary attacks against cryptosystems compliant to OpenPGP standard. Moreover, we describe a simplified mechanism to quickly test passphrases that might protect a specified private key. Only passphrases that pass this test complete the full (much more time consuming) validation procedure. This approach greatly reduces the time required to test a set of possible passphrases.

A fast, GPU based, dictionary attack to OpenPGP secret keyrings
We describe the implementation, based on the Compute Unified Device Architecture (CUDA) for Graphics Processing Units (GPU), of a novel and very effective approach to quickly test passphrases used to protect private keyrings of OpenPGP cryptosystems. Our combination of algorithm and implementation, reduces the time required to test a set of possible passphrases by three-orders of magnitude with...

متن کاملA High Capacity Email Steganography Scheme using Dictionary
The main objective of steganography is to conceal a secret message within a cover-media in such a way that only the original receiver can discern the presence of the hidden message. The cover-media can be a text, email, audio, image, and video, which can be transmitted through a public channel, such as the Internet. By extending the use of email among Internet users, the provision of email steg...
