  The blog post details the author's rediscovery of, and fascination with, the Usenet newsgroup alt.anonymous.messages. This group, designed for anonymous posting before the widespread adoption of anonymizing tools like Tor, relied on a server that stripped identifying headers. The author describes the unique culture that emerged within this space, characterized by stream-of-consciousness posts, personal confessions, emotional outpourings, and cryptic, often nonsensical messages, all contributing to an atmosphere of mystery and intrigue. The author highlights the historical significance of this group as a precursor to modern anonymous online communication and expresses a sense of nostalgia for this lost digital world.

  The blog post, titled "Alt.Anonymous.Messages Newsgroup," delves into the historical and functional aspects of the alt.anonymous.messages Usenet newsgroup. It begins by explaining the primary purpose of this group: providing a platform for anonymous posting. This anonymity, the author emphasizes, was a unique and valuable feature in the early days of the internet, predating readily available anonymizing tools like Tor. The post highlights the technical mechanism enabling this anonymity: the server stripped away identifying headers from incoming messages, replacing them with the generic "anon@anon.efga.org" address. This ensured that the true origin of a post remained hidden, offering a layer of privacy for users.

  The author then proceeds to discuss the practical implications of this anonymity. While acknowledging the potential for misuse – such as harassment, spamming, or illegal activities – the post emphasizes the legitimate uses of anonymous posting. These include whistleblowing, sharing sensitive information without fear of reprisal, and expressing unpopular or controversial opinions without the risk of personal attacks or censorship. The author suggests that the existence of alt.anonymous.messages provided a crucial space for free speech, particularly for individuals living under repressive regimes or facing societal pressure to conform.

  The technical operation of the newsgroup is further explored, explaining how messages posted to alt.anonymous.messages were propagated across the Usenet network. The author notes that despite the anonymity of the sender, the messages themselves were still subject to moderation and the rules of the individual news servers carrying the group. This meant that while the identity of the poster was protected, the content of the posts could still be scrutinized and potentially removed if deemed inappropriate.

  Finally, the post touches upon the eventual decline of alt.anonymous.messages. While not explicitly stated as the reason for decline, the author suggests the rise of more sophisticated anonymization methods, coupled with the general waning of Usenet's popularity, likely contributed to the group's diminished usage. The post concludes with a sense of nostalgia for this early form of online anonymity, recognizing its significance in the evolution of internet communication and its role in fostering a sense of freedom and privacy in the digital realm.

  The blog post "Let's talk about AI and end-to-end encryption" explores the perceived conflict between the benefits of end-to-end encryption (E2EE) and the potential of AI. While some argue that E2EE hinders AI's ability to analyze data for valuable insights or detect harmful content, the author contends this is a false dichotomy. They highlight that AI can still operate on encrypted data using techniques like homomorphic encryption, federated learning, and secure multi-party computation, albeit with performance trade-offs. The core argument is that preserving E2EE is crucial for privacy and security, and perceived limitations in AI functionality shouldn't compromise this fundamental protection. Instead of weakening encryption, the focus should be on developing privacy-preserving AI techniques that work with E2EE, ensuring both security and the responsible advancement of AI.

  The blog post "Let's talk about AI and end-to-end encryption" by Matthew Green on cryptographyengineering.com delves into the complex relationship between artificial intelligence and end-to-end encryption (E2EE), exploring the perceived conflict between allowing AI access to user data for training and maintaining the privacy guarantees provided by E2EE. The author begins by acknowledging the increasing calls to allow AI models access to encrypted data, driven by the desire to leverage this data for training more powerful and capable AI systems. This desire stems from the inherent limitations of training AI on solely public data, which often results in less accurate and less useful models compared to those trained on a broader dataset, including private user data.

  Green meticulously dissects several proposed solutions to this dilemma, outlining their technical intricacies and inherent limitations. He starts by examining the concept of training AI models directly on encrypted data, a technically challenging feat that, while theoretically possible in limited contexts, remains largely impractical and computationally expensive for the scale required by modern AI development. He elaborates on the nuances of homomorphic encryption and secure multi-party computation, explaining why these techniques, while promising, are not currently viable solutions for practical, large-scale AI training on encrypted datasets.

  The post then transitions into discussing proposals involving client-side scanning, often framed as a means to detect illegal content, such as child sexual abuse material (CSAM). Green details how these proposals, while potentially well-intentioned, fundamentally undermine the core principles of end-to-end encryption, effectively creating backdoors that could be exploited by malicious actors or governments. He meticulously outlines the technical mechanisms by which client-side scanning operates, highlighting the potential for false positives, abuse, and the erosion of trust in secure communication systems. He emphasizes that introducing any form of client-side scanning necessitates a shift away from true end-to-end encryption, transforming it into something closer to client-to-server encryption with client-side pre-decryption scanning, thereby compromising the very essence of E2EE's privacy guarantees.

  Furthermore, Green underscores the slippery slope argument, cautioning against the potential for expanding the scope of such scanning beyond CSAM to encompass other types of content deemed undesirable by governing bodies. This expansion, he argues, could lead to censorship and surveillance, significantly impacting freedom of expression and privacy. The author concludes by reiterating the importance of preserving end-to-end encryption as a crucial tool for protecting privacy and security in the digital age. He emphasizes that the perceived tension between AI advancement and E2EE necessitates careful consideration and a nuanced approach that prioritizes user privacy and security without stifling innovation. He suggests that focusing on alternative approaches, such as federated learning and differential privacy, may offer more promising avenues for developing robust AI models without compromising the integrity of end-to-end encrypted communication.

  Hacker News users discussed the feasibility and implications of client-side scanning for CSAM in end-to-end encrypted systems. Some commenters expressed skepticism about the technical challenges and potential for false positives, highlighting the difficulty of distinguishing between illegal content and legitimate material like educational resources or artwork. Others debated the privacy implications and potential for abuse by governments or malicious actors. The "slippery slope" argument was raised, with concerns that seemingly narrow use cases for client-side scanning could expand to encompass other types of content. The discussion also touched on the limitations of hashing as a detection method and the possibility of adversarial attacks designed to circumvent these systems. Several commenters expressed strong opposition to client-side scanning, arguing that it fundamentally undermines the purpose of end-to-end encryption.

  The Hacker News post "Let's talk about AI and end-to-end encryption" has generated a robust discussion with several compelling comments. Many commenters grapple with the inherent tension between the benefits of AI-powered features and the preservation of end-to-end encryption (E2EE).

  One recurring theme is the practicality and potential misuse of client-side scanning. Some commenters express skepticism about the feasibility of truly secure client-side scanning, arguing that any client-side processing inherently weakens E2EE and creates vulnerabilities for malicious actors or governments to exploit. They also voice concerns about the potential for function creep, where systems designed for specific purposes (like detecting CSAM) could be expanded to encompass broader surveillance. The chilling effect on free speech and privacy is a significant concern.

  Several comments discuss the potential for alternative approaches, such as federated learning, where AI models are trained on decentralized data without compromising individual privacy. This is presented as a potential avenue for leveraging the benefits of AI without sacrificing E2EE. However, the technical challenges and potential limitations of federated learning in this context are also acknowledged.

  The "slippery slope" argument is prominent, with commenters expressing worry that any compromise to E2EE, even for seemingly noble purposes, sets a dangerous precedent. They argue that once the principle of E2EE is weakened, it becomes increasingly difficult to resist further encroachments on privacy.

  Some commenters take a more pragmatic stance, suggesting that the debate isn't necessarily about absolute E2EE versus no E2EE, but rather about finding a balance that allows for some beneficial AI features while mitigating the risks. They suggest exploring technical solutions that could potentially offer a degree of compromise, though skepticism about the feasibility of such solutions remains prevalent.

  The ethical implications of using AI to scan personal communications are also a significant point of discussion. Commenters raise concerns about false positives, the potential for bias in AI algorithms, and the lack of transparency and accountability in automated surveillance systems. The potential for abuse and the erosion of trust are recurring themes.

  Finally, several commenters express a strong defense of E2EE as a fundamental right, emphasizing its crucial role in protecting privacy and security in an increasingly digital world. They argue that any attempt to weaken E2EE, regardless of the intended purpose, represents a serious threat to individual liberties.
