Samantha uses the ECDSA signature scheme with elliptic curve

 

Transcribed Image Text:

E: Y² = X³ + 13X +37 over F7331 and point G = (3297,3109) with order 101. Her public verification key is V = (3865, 4318). Victor claims that Samantha has signed each of the documents d=10, d'= 20, d" = 30 and that the associated signatures are (S₁, S₂) = (66,52), (S₁,S₂) (97,22). (ST.S₂) = (27,21) which of these are valid signatures? = 4 E: Y² = X³ + 13X +37 over F7331 and point G = (3297,3109) with order 101. Her public verification key is V = (3865, 4318).

The valid signatures are S1 S2 6652 and S1 S2 2721 To verify the validity of the signatures we need to calculate the following 1 Calculate the value o... View the full answer
