In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Pairings are a relatively new cryptographic tool which have been the object of many arithmetic works. In the last few years some of the pairings have become obsolete because of the progress on the underlying problem of discrete logarithm in finite fields. We propose ourselves to make a list of pairings constructions, to explain their advantages but also their weaknesses. The sporadic curves are vulnerable to the Logjam attack and have never been a popular choice. The small characteristic curves allow a very good arithmetic but are the target of a quasi-polynomial algorithm. The pairings where the characteristic has a low Hamming weight, which eliminate the cost of modular reductions, have been the object of special attacks. When the embedding degree is composite the one can use the tower field arithmetic but there are also tower field attacks. We will conclude by a list of safe pairings and the perspectives on their arithmetic performances.
