10.1.1.3.2. dcsim.utils.FSignHash module

class dcsim.utils.FSignHash.FSignHash(name)

Bases: dcsim.framework.TrustedThirdPartyBase.TrustedThirdPartyBase

A authentication service based on hash with secret keys

each node has one secret key and the signature is generated by

signature = SHA256(node’s secret key || message)

where || is concatenation operator of bytes

register(caller: <function NewType.<locals>.new_type at 0x1087282f0>) → None

round_action(round: int) → None

sign(caller: <function NewType.<locals>.new_type at 0x1087282f0>, message: bytes) → str

verify(caller: <function NewType.<locals>.new_type at 0x1087282f0>, signature: str, message: bytes, sender_id: <function NewType.<locals>.new_type at 0x1087282f0>) → bool

10.1.1.3.3. dcsim.utils.FSignRSA module

class dcsim.utils.FSignRSA.FSignRSA(name)

Bases: dcsim.framework.TrustedThirdPartyBase.TrustedThirdPartyBase

a authentication service based on RSA public key algorithm

each node has a key pair, private key for sign and public key for verify

The performance is much worse than hash-based authentication service. It is a example to illustrate how to use AuthenticationServiceBase to

implement a public key algorithm based authentication serivce.

register(caller: <function NewType.<locals>.new_type at 0x1087282f0>) → None

round_action(round: int) → None

sign(caller: <function NewType.<locals>.new_type at 0x1087282f0>, message: bytes) → str

verify(caller: <function NewType.<locals>.new_type at 0x1087282f0>, signature: str, message: bytes, sender_id: <function NewType.<locals>.new_type at 0x1087282f0>) → bool
