Victory! End-to-End Encrypted RCS Comes to Apple and Android Chats
完整原文
This week, Apple released iOS 26.5, an update that supports end-to-end encryption for Rich Communication Services (RCS), meaning conversations between Android and iPhone will soon be encrypted in the default chat apps. This has been a long time coming, and is a welcome delivery on a promise both Google and Apple made. With this update, conversations that take place between Apple’s Messages app and Google Messages on Android will be end-to-end encrypted by default, as long as the carrier supports both RCS and encrypted messages (you can find a list of carriers here). RCS messages are a replacement for SMS, and in 2024 Apple started supporting it, making for a marked improvement in the quality of images and other media shared between Android and iPhones. Now, those conversations can also benefit from the increased privacy and security that end-to-end encryption offers, making it so neither Google, Apple, nor the cellular carriers have access to the contents of messages. This feature comes courtesy of both Apple and Google supporting the GSMA RCS Universal Profile 3.0, which implements the Messaging Layer Security protocol for encryption. Metadata will likely still be collected and stored for these conversations, making alternatives like Signal still a better option for many conversations. Likewise, if you back up those conversations to the cloud, they may be stored unencrypted unless you enable Advanced Data Protection on iOS (Google Messages end-to-end encrypts the text of messages in backups, but not the media, so we’d like to see a similar offering as ADP on Android). Still, this is a significant step forward for the privacy of millions of conversations worldwide. End-to-end encrypted RCS messaging is still marked as beta on Apple devices, likely because the rollout is dependent on carriers as well as the Android phone running the most recent version of Google Messages. It might take some time before you get this feature in your chats and until you do, remember that the conversations are not protected with end-to-end encryption. But once everyone in the conversation is on the right software version and the carrier support is implemented, you will see a lock icon and the text, “Encrypted” at the top of the conversation for any chats you have over RCS, as seen here: We applaud Apple and Google for getting this across the finish line and Encrypting It Already! More companies should take these sorts of difficult but necessary steps to protect the privacy of our conversations and our data.
归纳
苹果本周发布iOS 26.5更新，支持富通信服务（RCS）的端到端加密，这意味着安卓与iPhone之间的默认聊天应用将实现加密通信。该功能基于GSMA RCS通用配置文件3.0，采用消息层安全协议进行加密，需运营商同时支持RCS和加密消息。RCS作为短信的替代方案，自2024年苹果支持以来已改善跨平台媒体质量，此次加密进一步提升了隐私安全性，谷歌、苹果及运营商均无法读取消息内容。但元数据仍可能被收集，云备份需启用高级数据保护（iOS）或注意媒体未加密（安卓）。该功能在苹果设备上仍标记为测试版，全面推广需时间。
点评
跨平台端到端加密虽提升通信隐私，但元数据收集与云备份加密差异可能违反《个人信息保护法》下的最小必要原则和告知同意要求。

实务启示
中国法律人应审查企业通信产品是否在元数据收集和云备份环节履行充分告知义务，并评估加密技术对执法协助义务的潜在影响。
