| | | | | JSON Web Tokens or JWTs are used by some web applications instead of traditional session cookies. Because of their statelessness and the signature implementation there are some security issues that are specific to JWTs. This post describes some ways you can verify that a JWT implementation is secure. | |

| | | | | Although it is one of the most popular signature schemes today, ECDSA presents a number of implementation pitfalls, in particular due to the very sensitive nature of the random value (known as the nonce) generated as part of the signing algorithm. It is known that any small amount of nonce exposure or nonce bias can in principle lead to a full key recovery: the key recovery is then a particular instance of Boneh and Venkatesan's hidden number problem (HNP). That observation has been practically exploited in many attacks in the literature, taking advantage of implementation defects or side-channel vulnerabilities in various concrete ECDSA implementations. However, most of the attacks so far have relied on at least 2 bits of nonce bias (except for the special ... | |
