Title: Cobo Wallet:Core Component of Security Chip Open Sourced Post by: Ann1989 on January 15, 2019, 10:17:40 AM The core component of the Cobo Vault's security chip has been open sourced on GitHub. https://github.com/cobowallet/Cobo-Vault-Security-Chip-Firmware
After looking at the source code, I saw how much the development team values security. In the source code, when using critical data comparison, custom memcmp_ATA () is used instead of the C language implemention memcmp(). Code: /**memcmp Anti-Timing-Attack*/ |
