Cryptography’s most notorious pirate , Luca De Feo, returns to Real World Crypto to discuss the dangers of ambiguity in cryptographic standards, based on his work with Bertram Poettering and Alessandro Sorniotti. WebDiffie–Hellman key exchange. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key. After obtaining an authentic copy of each other's public keys, Alice and Bob can compute a shared secret offline. The shared secret can be used, for instance, as the key for a symmetric cipher. flx cricket

WebTo understand where the security problem discovered by De Feo, Poettering and Sorniotti hides, we need to have a deeper look at the ElGamal public-key encryption scheme which is one of the required public-key algorithms specified in RFC4880 (the technical document that describes how OpenPGP should operate).

WebElGamal encryption has been used in many different contexts, chiefly among them by the OpenPGP standard. Despite its simplicity, or perhaps because of it, in reality there is a large degree of ambiguity on several key aspects of the cipher.

WebThe ElGamal implementation in Libgcrypt before 1.9.4 allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack …
