An untraceable temporal-credential-based two-factor authentication scheme using ECC for wireless sensor networks

Cryptanalysis of an Untraceable Temporal-Credential-Based Two-Factor Authentication Scheme Using ECC for Wireless Sensor Networks

“…In this section, we will show that Jiang et al's scheme [10] is vulnerable to malicious user impersonation attack and node capture attack and suffer from forward security problem, low efficiency problem, no password change phase problem and time synchronization problem.…”

“…Based on these, He et al improved Xue et al's scheme. However, Jiang et al [10] revealed that He et al's scheme is susceptible to stolen smart card attack and prone to tracking attack, and proposed an improved scheme in 2016.…”

“…[10]. Their scheme includes three phases: registration phase, login phase and authentication phase; and involves three entities: users, gate-way node (GW) and sensor nodes.…”

Cryptanalysis of Three Password-Based Remote User Authentication Schemes with Non-Tamper-Resistant Smart Card

“…In other words, authentication ensures that only the legitimate users can access the resources on the target server. And authentication protocols have been widely used for various fields, including cloud computing, E-Health, and wireless sensor [1][2][3][4].…”

“…They have become an important criterion of an ideal remote authentication scheme. Most of remote user authentication schemes [4,[40][41][42] are designed and evaluated according to them, while none of the schemes could actually satisfy them simultaneously. Therefore, many researchers begin to pay more attention to e a l 2 Password dependent 3 No verification table 4 Freely chosen password by the users 5 F o r w a r d s e c r e c y 6…”
