What does Jesus mean by God’s name?

in Kerygmania
I’m looking at John 17, where Jesus is praying to the Father, and several times he mentions “your name”—for example, “I have kept them in your name” or “your name, which you have given me,” or “I have manifested your name to the people who you gave me.” What exactly does he mean by “your name” in those formations? I mean, is it just a colorful way of saying “You” or “your will” or??? I’m not coming up with a really coherent idea, as you can tell. But it’s clearly very important…
Also, how does it differ from “your word,” which also shows up several times?
Help.

I also think of passages like Isaiah 43 (“Do not fear, for I have redeemed you; I have called you by name; you are mine.”)
In the case of John 17, I think perhaps what Jesus says has to be considered in the broader context of John—the prologue, the number of times Jesus uses “I Am” about himself, etc. I think it’s a way Jesus is yet again identifying himself with YHWH, describing how he has revealed God’s nature and identity, and describing how “those you have given me” have been claimed by God as belonging to God and bearing God’s name, just as a child might bear their father’s name (whether a modern surname or something like Yeshua bar Yosef).
1 I know the usual translation is “take the name of the Lord your God in vain,” which is often understood to mean “use” or “speak the name of the Lord your God in vain.” But my understanding is that the Hebrew carries a connotation of “take” in the sense of “carry” or “bear,” as in “take this with you.”
Everything in me wants to claim that "to manifest God's name" is to incarnate God, to reveal God. Not just to reveal some character or quality of God, but to show God forth in a "real" way. I'm grappling for words, and I'm quite sure that someone will come along and beat me up, but that's OK.
In some cultures, if you know someone's true name, you have power over the person. Clearly, a name is not just a convenient handle, it is, in some way, the essence of the person. I wonder whether manifesting God's name means manifesting the reality of God.
Manifested there translates the Greek Ἐφανέρωσά which simply means to reveal or to make known. At one level you could just see ‘your name’ as a reverent periphrastic for ‘you’ - ‘I have made you known’ or ‘I have revealed you’.
In Jesus Christ God reveals himself to humankind in a way that we can truly comprehend. And I think that coheres with what @questioning has posted above.
That also makes me think of the exchange between Moses and God in Exodus 3.13-14 where again giving the name appears to be something which reveals the ‘person’ named.
Same with God?
With the names of human beings being used to convey so much information about who someone is, or what their parents aspire for them, how much more does the name of God convey about who God is? The name of God carries His whole character. He is loving, faithful, forgiving ... being kept in that name is an assurance of our salvation. Making that name known ("manifest") isn't just telling people how to refer to a deity, it's demonstrating who God is by showing all of His character in how we (collectively) behave to others so that in us people see who God is.
Yes, the use of “name” in English here does not convey the import does it. The context suggests that believers are maintained in a secure state and protected from negative interference. There is an issue of ownership. The Lord states that these are exclusively his own. The name here possibly suggests a signature of authority whereby a covenant is sealed or a contract authenticated legally.
Yep. It is a kind of confirming factor.. if you see Baptism as a sealing or signature of the believers security. A kind of conflation of action with label where use of the ‘name’ confirms the assurance the believer has. Looking back at various covenantal transactions there was always a signature factor such as circumcision or the rainbow.
Baptism would be just getting wet, no more effective than a bath, if it wasn't for God's name being invoked. When we're baptised in the name of the Father, Son and Holy Spirit the water is symbolic, but it's also a real event in which God effectively adds His signature to say "I forgive and accept you, you are mine, no matter what happens I will be faithful and won't let you go".
Maybe that's why I'm having trouble with the name thing, I don't know. "Transaction" just sits oddly with me.
I don't think what @MPaul and @Alan Cresswell and others have posted elides or negates that, even though I may not put things in quite the same way that they have.
I like what @Nick Tamen wrote upthread about the 'I ams' and the invocation of God's 'name' implying the deepest possible identification between God and the believer.
