Research on Key Technology for Data Cache Timing Attack on DSA

摘要：

　　Gaining the value of k is a key technology for sidechannel attack on DSA.In order to recover the private key of a DSA signature,this paper proposes a method based on datacache timing attack.That is getting side channel information about a random number k used in a signature first and then recover the private key x from this.We mainly introduces the principle of data-cache timing attack and describe the method of gaining said k.
