Following NIST's finalization of PQC standards [2], ML-DSA has been established as the primary quantum-resistant signature standard. As quantum computing advances, legacy algorithms like RSA are becoming increasingly vulnerable and are slated for replacement by 2035 [3]. By adopting ML-DSA for IPA library signing, this work secures the long-term integrity of the IPA library and aligns libcamera with the latest NIST security frameworks.

Changes in v3: - Add "utils::scope_exit ctxGuard([&] { EVP_MD_CTX_free(ctx); });" and rename the variable name from "ctx_dsa" to "ctx". - Drop the debug logs from the pub_key.cpp. - Resolve "[: RSA: unexpected operator" in utils/gen-ipa-priv-key.sh Changes in v2: - Change the meson option name from "fips" to "isp-signature-algo". - Drop the debug print in the pub_key.cpp. - One line command "openssl pkeyutl" is used to sign the IPA library.
