Consider the following protocol:

A → B : <A, {K}pk(B)>

B → A : <B, {K}pk(A)>

First, A generates a fresh key K and sends it encrypted with the public key of B. Only B will be able to decrypt this message. In this way, B learns K and B also knows that this message comes from A as indicated in the first part of the message he received. Hence, B

answers to A by sending again the key, this time encrypted with the public key of A.

Show that an attacker can learn the key K generated by an honest agent A to another honest

agent B.

My boyfriend and I are in a long distance relationship, have been together for 2 and a half years (was not long distance to begin with however). We always said we would get married. We love each other and we're already committed to each other, just waiting to be back in the same city.

However, I am afraid that we have already entered the 'married couple' stage in the sense that nothing is new or exciting. For example, we didn't do anything for Valentine's Day. It was just another day to him. We barely talk as it is, and yesterday was no exception.

Can I fix this? Is he already so comfortable that he doesn't feel the need to try anymore?

Thanks!

There are condoms located in some of the bathrooms in the residence halls, and I know they are restocked once a week, I just don't know what day.

Thanks!

I use liquid foundation first, then a concealer, and then a mineral powder foundation. I have used cream foundation before, in place of the liquid but it did the same thing. Both leave my face dry. It seems to be the liquid/cream foundation that does it. I make sure I really moisturize before, but it doesn't seem to help. It is mostly around my nose, at least that is where it begins. It makes it look like my skin is peeling. Also, throughout the day, it starts to look like the foundation is breaking or cracking....what do I do?

Thanks!

My boyfriend just recently told me that he no longer finds me to be physically attractive - the reasons being that I have put on a little weight and I have moderate acne (these are both very true and valid). This obviously makes me so sad, especially because in the past he has told me that I am perfect just as I am and he loves me no matter what and I'll always be beautiful yada yada. So now I feel like I've been lied to. Now I am beginning an exercise/dieting routine and am trying different things for my acne, but in the meantime am wearing foundation to cover it up as best I can.

So basically this is how I am feeling. I want to make these things better for him, I really do. But at the same time I am so hurt. I don't want to get intimate with him at all, and by his logic he shouldn't want to either, if he doesn't even find me attractive. But then again, I feel like once I am pretty again, I won't want to get intimate with him, because I feel like he won't deserve it. If he doesn't love my body as it is now, why should I let him love it when it's perfect? Regardless of my physical appearance it is still me, the girl he claims to love. I feel like a ***** for feeling this way, but I can't see myself ever making love to him again.

Thoughts? Thanks everyone.

His reasons are that I have put on a little weight (10 pounds max) and have some acne on my face. I have been exercising and dieting for over a month now and I bought some rather expensive acne treatments. I am trying my best. Guys? Is it normal for you to feel this way? Or is there something wrong with me?

I have been with my boyfriend over a year now, and we are very in love. We have recently made love for the first time, and many times since. We absolutely cannot get pregnant right now so we said we would stop the sex. But he knows just where to kiss me to get me in the mood, even if I've already told him no. So beforehand, and even during, I am happy with my decision to make love to him. But once it is over, I feel regret, and sadness even. It really makes me sad because he doesn't seem to want to have anything to do with me afterwards (meaning within the same night). He just turns on the tv and almost ignores me. If I try to cuddle with him or kiss him he doesn't cuddle or kiss back, but just ignores me. I don't know if this is normal or if this is how I'm supposed to feel. Thanks.

Today my boyfriend and I were messin around and he started to finger me. I got really into it and pushed his arm really hard. His fingers went in farther than they ever had (yes, I am a virgin). I felt this excruciating pain like he had hit a wall inside my vagina or something. I've never experienced this before. Is this normal? Is it supposed to hurt? Thank you for any help you can provide!

Yesterday all of a sudden I had this severe pain in my anus. It feels like pressure or fullness - like a LOT of gas, but there is nothing there. It becomes worse when I sit down and when i walk (specifically when I step forward with my left foot). Should I be concerned? I am a female, if that is important. And in case it is important - NO nothing has ever been up there. Thanks for any help!

So I go an article from The Atlantic online and I need to cite it. Should it be cited as a:

magazine article

newspaper article

scholarly journal article

web magazine article

OR

online scholarly journal article that also appears in print?

I am so confused so any help is appreciated. Thank you!

I'm thinking along the lines of something like PostSecret, but not that because you cannot submit emails, and those are usually one sentence stories. And by stories, I don't mean made up stories, I mean just to tell someone something that you need to let out. If that makes sense... Thanks for any help!

Lately when I put my contacts in, they have burned my eyes for a minute. Then today I realize that there are salt crystals in the bottom of my contact lens case. Just wondering if I need to worry about my eyes or anything, and how the salt crystals formed. Thanks!!!

Okay so I know that girls are supposed to shave their legs and underarms, and pubic hair if they so desire. But suppose a girl has hair on her chest/stomach/back? It's like vellus hair, so its light and thin, kind of like the hair on your thighs. Do all girls have this? Or only some? And are they supposed to shave that too? Sorry for my ignorant questions, but thanks for taking the time to answer me.

I already know some Spanish, but I would like to become fluent in it. What is the best website that is free and actually works? I would also like to learn French, German, and Italian, but my primary goal is to learn Spanish. I have seen these websites, but I don't know if they are good:

Mango

Babbel

Live Mocha

Speak7

Do these work? Are there any websites you all know of that work? Any help is appreciated and thank you!!!
