Recovering OpenSSL ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack
We illustrate a vulnerability introduced to elliptic curve cryptographic protocols when implemented using a function of the OpenSSL cryptographic library. For the given implementation using an elliptic curve E over a binary field with a point G ∈ E, our attack recovers the majority of the bits of a scalar k when kG is computed using the OpenSSL implementation of the Montgomery ladder. For the E...
متن کاملThe Aspects of ECDSA
Digital signatures are used world wide to verify the authenticity of messages and confirm that they have not been altered in transmission [2]. The Digital Signature Algorithm (DSA) is a Digital Signature Standard for the Federal Information Processing Standard and uses public key cryptography [1]. The Elliptic Curve Digital Signature Algorithm (ECDSA) is a version of DSA using elliptic curves. ...
متن کاملMinerva Rooms
Each of the Minerva houses has a seminar room that is equipped with a limited amount of technology. In keeping with the President's initiative to build a close relationship between academic and student life, the rooms are available to both students and faculty to use. each room contains a motorized projection screen, a ceiling-mounted data projector, and a DVD/VCR combo unit. A panel in the roo...
متن کاملNeologisms, Nonces and Word Formation
Neologism dictionaries celebrate the influence of science and technology on language – how scientists and technologists add to the stock of words, and occasionally, add new grammatical structures. There are two claims made in the literature on neologisms: First, that borrowings, from classical languages and ‘prestige’ languages are widespread in the science and technology literature. Second tha...
متن کاملAccelerated Verification of ECDSA Signatures
Verification of ECDSA signatures is considerably slower than generation of ECDSA signatures. This paper describes a method that can be used to accelerate verification of ECDSA signatures by more than 40% with virtually no added implementation complexity. The method can also be used to accelerate verification for other ElGamal-like signature algorithms, including DSA.
