A Fixed-Latency Architecture to Secure GOOSE and Sampled Value Messages in Substation Systems
; ; Bidarte Peraita, Unai
; ; (IEEE, 2021-03-26)
International Electrotechnical Commission (IEC) 62351-6 standard specifies the security mechanisms to protect real-time communications based on IEC 61850. Generic Object Oriented Substation Events (GOOSE) and Sampled Value ... -
Caracterización de la tolerancia a fallos de circuitos implementados en FPGAs
(2019-05-17)Las FPGAs (Field-Programmable Gate Array) y los SoC (System-on-chip) basados en FPGA son dispositivos electrónicos configurables en campo (in field), que ofrecen la posibilidad de desarrollar un circuito a medida con un ... -
Diseño e implementación de nuevas funcionalidades en emulador de canal RF sobre dispositivo con multiprocesamiento asimétrico y lógica programable
(2023-05-02)En la industria 4.0, se quiere fomentar el uso de tecnologías inalámbricas. Sin embargo, debido a la naturaleza de la propagación inalámbrica, aún es difícil cumplir con los requisitos de fiabilidad, latencia y determinismo ... -

Encryption AXI Transaction Core for Enhanced FPGA Security
; ; Muguira Urtubi, Leire; Bidarte Peraita, Unai ; (MDPI, 2022-10-18)
The current hot topic in cyber-security is not constrained to software layers. As attacks on electronic circuits have become more usual and dangerous, hardening digital System-on-Chips has become crucial. This article ... -
Evaluating Latency in Multiprocessing Embedded Systems for the Smart Grid
Alonso Salazar, Sara; ; ; Bidarte Peraita, Unai ; Muguira Urtubi, Leire (MDPI, 2021-06-05)
Smart grid endpoints need to use two environments within a processing system (PS), one with a Linux-type operating system (OS) using the Arm Cortex-A53 cores for management tasks, and the other with a standalone execution ... -
Fast and efficient address search in System-on-a-Programmable-Chip using binary trees
; Bidarte Peraita, Unai; Muguira Urtubi, Leire ; ; (Elsevier, 2021-12)
One processing task in Ethernet nodes is to manage Media Access Control (MAC) addresses: search, insert new, and delete old ones. For this purpose, Content-Addressable Memorys (CAMs) offer low latency and no collisions; ... -
Functional Verification for SEU Emulation in FPGA Designs
; Bidarte Peraita, Unai; ; ; Matallana Fernandez, Asier (2014-09-17)
In this paper techniques to detect failures in a FPGA are presented and their application to SEU (Single Event Upset) emulation applications is discussed. SEU emulation in FPGAs consists on programming the device with a ... -
Interrupt Latency Accurate Measurement in Multiprocessing Embedded Systems by Means of a Dedicated Circuit
Alonso Salazar, Sara; Muguira Urtubi, Leire ; ; ; Bidarte Peraita, Unai (MDPI, 2024-04-24)
Modern multiprocessing embedded applications require, in many cases, two different environments on the same platform: one that meets real-time requirements and another one with a general purpose operating system. Although ... -
MACsec Layer 2 Security in HSR Rings in Substation Automation Systems
; ; Araujo Parra, José Ángel; ; Bidarte Peraita, Unai (MDPI, 2017-01-31)
The smart-grid concept takes the communications from the enclosed and protected environment of a substation to the wider city or nationwide area. In this environment, cyber security takes a key role in order to secure the ... -
