WebA BLS digital signature—also known as Boneh–Lynn–Shacham (BLS)—is a cryptographic signature scheme which allows a user to verify that a signer is authentic.. The scheme uses a bilinear pairing for verification, and signatures are elements of an elliptic curve group. Working in an elliptic curve group provides some defense against index calculus attacks … Webric cryptographic schemes. First we generalize some existing cryptographic schemes to the context of a group action on a set, and discuss their security. We then apply results of the complex multiplication theory to implement the proposed crypto-graphic schemes. Namely we use the action of the ideal class group CL(OK) of

As with all security-related systems, it is important to identify potential weaknesses. Aside from poor choice of an asymmetric key algorithm (there are few which are widely regarded as satisfactory) or too short a key length, the chief security risk is that the private key of a pair becomes known. All security of messages, authentication, etc., will then be lost. All public key schemes are in theory susceptible to a "brute-force key search attack". However, s…
