Performance Evaluation and Analysis of IEC 62351-6 Probabilistic Signature Scheme for Securing GOOSE Messages

A Chosen Messages Attack on the ISO/IEC 9796-1 Signature Scheme

We introduce an attack against the ISO/IEC 9796–1 digital signature scheme using redundancy, taking advantage of the multiplicative property of the RSA and Rabin cryptosystems. The forged signature of 1 message is obtained from the signature of 3 others for any public exponent v. For even v, the modulus is factored from the signature of 4 messages, or just 2 for v = 2. The attacker must select ...

Cyber Security Practical considerations for implementing IEC 62351

Two trends are currently changing substation automation systems: IEC 61850 and the need for increased cyber security. IEC 61850 has gained global acceptance by both vendors as well as customers. Cyber security on the other hand has quickly become one of the most dominant topics for control systems in general and electrical utilities in particular. The combination of the two, securing IEC 61850 ...

An Efficient Signature Scheme for Securing Multicast Communication

Multicasting is an efficient communication mechanism for group oriented applications such as video conferencing, distance learning etc. Assuring certain level of security over multicast communication has become vital in Internet applications. Various cryptographic algorithms have been used to provide different security services. One among the cryptographic scheme is the digital signature which ...

1 Performance Evaluation of IEC 61850 Process

The paper presents the performance of a novel distributed bus differential protection scheme, which utilizes independent multi-principle advanced protection algorithms, including differential percent slope, delta phase directional comparison, rate of change of differential (ROCOD) currents, delta phase directional comparison on neutral current differential, and a check zone to secure the electr...
