The following errata report has been verified for RFC7748, "Elliptic Curves for Security". -------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid7625 -------------------------------------- Status: Verified Type: Technical Reported by: Tomasz Mioduszewski <newmiodek@proton.me> Date Reported: 2023-08-31 Verified by: Stanislav Smyshlyaev (IRSG) Section: 5 Original Text ------------- swap ^= k_t Corrected Text -------------- swap = swap XOR k_t Notes ----- The '^' symbol is used inconsistently. In the line `swap ^= k_t` this symbol means the XOR operation, while later, e.g. in line `x_3 = (DA + CB)^2`, it indicates exponentiation. Pseudocode in this document also denotes the XOR operation in the following way: `x_2 = x_2 XOR dummy`. The inconsistent use of the '^' symbol may cause confusion. If one were to perform the operation `swap = swap (to the power of) k_t` instead of `swap = swap XOR k_t`, they would get incorrect results. -------------------------------------- RFC7748 (draft-irtf-cfrg-curves-11) -------------------------------------- Title : Elliptic Curves for Security Publication Date : January 2016 Author(s) : A.
